Planowanie i zarządzanie ruchem w systemach transportu szynowego należy do najbardziej złożonych wyzwań w transporcie publicznym. Każde zakłócenie - awaria, opóźnienie czy nieprzewidziane zdarzenie - wymaga szybkiego przeliczenia rozkładów jazdy, co w praktyce jest trudne do osiągnięcia przy użyciu klasycznych metod obliczeniowych. Dlatego rośnie zainteresowanie alternatywnymi paradygmatami, w tym komputerami kwantowymi i metodami hybrydowymi. Badania prowadzone wspólnie przez naukowców z Polski i USA na przykładzie sieci Baltimore Light RailLink pokazały, że komputery kwantowe, mimo ograniczeń typowych dla ery NISQ (Noisy Intermediate-Scale Quantum pl. kwantowe o średniej skali wielkości obarczone szumem), mogą generować realistyczne warianty rozkładów jazdy. Zamiast jednego sztywnego planu, urządzenia kwantowe tworzą zestaw scenariuszy, które lepiej odzwierciedlają niepewność i losowość w ruchu aglomeracyjnym. Szczególnie obiecujące mogą tu okazać się podejścia hybrydowe, łączące moc klasycznych algorytmów z elastycznością metod kwantowych. Na tym tle doświadczenia polskich naukowców, zwłaszcza we współpracy z Kolejami Śląskimi, wskazują kierunki praktycznego zastosowania. Harmonogramowanie obiegów taboru - w przypadku operatora dysponującego około 60 elektrycznymi zespołami trakcyjnymi i uruchamiającego około 500 pociągów dziennie - stanowi typowy przykład problemu o ogromnej złożoności. Uwzględnienie potrzeb pasażerów (dopasowanie liczby miejsc, punktualność, elastyczne reagowanie na zakłócenia) sprawia, że metody kwantowe dysponują szczególnym potencjałem. Artykuł omawia przykłady międzynarodowe i krajowe, wskazując na potencjał komputerów kwantowych i inspirowanych fizyką metod optymalizacyjnych w budowaniu bardziej odpornych, elastycznych i przyjaznych pasażerowi systemów transportu szynowego.

Planning and managing traffic in rail transport systems is among the most complex challenges in public transportation. Every disruption - whether a breakdown, delay, or unforeseen incident - requires rapid recalculation of timetables, which in practice is difficult to achieve using classical computational methods. This is why there is growing interest in alternative paradigms, including quantum computing and hybrid approaches. Research conducted jointly by scientists from Poland and the United States, using the Baltimore Light RailLink as a case study, has shown that quantum computers, despite the limitations typical of the NISQ (Noisy Intermediate-Scale Quantum) era, can generate realistic timetable variants. Instead of producing a single rigid schedule, quantum devices generate sets of scenarios that better capture uncertainty and randomness in metropolitan traffic. Particularly promising in this respect are hybrid approaches that combine the computational power of classical algorithms with the flexibility of quantum methods. Against this background, Polish experiences - especially in cooperation with Koleje Śląskie (Silesian Railways) - point to directions for practical application. Rolling stock circulation scheduling, for an operator managing 60 electric multiple units (EMUs) and operating around 500 trains daily, represents a typical example of a highly complex problem. Taking into account passenger needs (matching capacity to demand, punctuality, and flexible response to disruptions) makes quantum methods especially valuable. The article discusses international and domestic examples, highlighting the potential of quantum computers and physics-inspired optimization methods in building more resilient, flexible, and passenger-friendly rail transport systems.

The maritime inventory routing problem (MIRP) is an optimization task aimed to increase the efficiency of the distribution of bulk products by sea. It combines the routing of a fleet of heterogeneous vessels between capacitated supplying and demanding ports with the inventory handling at the involved facilities. We consider a well-studied and general MILP-model variant and introduce modelling adaptations to reduce end-of-horizon effects. The primary goal is to investigate the capabilities and limitations of current large-scale quantum-based optimization platforms as a new solution method for MIRPs. We thus benchmark the computational performance of D-Wave’s quantum-classical hybrid solver on our model by comparing it to results obtained with CPLEX as a classical state-of-the-art solution method. The test instances cover a range of different parameter scales, ranging from 2 to 4 ports, fleet size of 2 to 7 vessels and up to 45 discrete time periods. The benchmark results show that the hybrid system fails to find solutions in the same time as CPLEX for about half the problem instances. In particular, it struggles to explore tight solution spaces of larger instances. The hybrid solutions that were found vary in quality, averaging to about 65% to 75% of the classically computed objective values. For improved results we believe that the problem formulation needs to be changed to a regime better suited for the hybrid solver, e.g. by incorporating quadratic terms.

The efficient management of energy resources in modern smart grids is becoming increasingly critical due to growing energy demands and the need for sustainability. To address these challenges, this study introduces a novel hybrid optimization approach that combines quantum computing techniques with classical algorithms. By leveraging the strengths of Variational Quantum Algorithms (VQAs) alongside traditional optimization methods for preprocessing and postprocessing, the proposed framework offers an effective solution to complex combinatorial problems inherent in smart grid operations. Experimental evaluations on simulated grid models demonstrate significant improvements in energy efficiency—up to 25%—compared to conventional optimization techniques. This work highlights the transformative potential of quantum computing in advancing the operational efficiency of energy systems and ensuring scalability for future smart grid applications.

Scientists involved in building quantum computers are currently facing many physical difficulties. Creating qubits, manipulating them and reading their state requires a lot of experience. This paper describes an optical laser system as a test platform for quantum-optical control that enables effective manipulation of an emulated quantum bit. Importantly, it is a reproduction of the system controlling the optical path in real ion traps. This solution makes it possible to study the phenomena occurring in such systems and to learn about the wide range of problems that a designer and an operator of quantum systems may encounter, even before they start building them. The optical system presented in the article uses, among others, a 532 nm laser, acousto-optic modulators (AOMs), ultrafast light detectors, and a programmable FPGA chip. The entire optical system was then attached to the QUBIT emulator and thoroughly tested. The article describes the design and operation of the proposed optical system and shows an example of how to control it using a Python script.

Students attending the lecture on quantum information technology are mostly at the level of completing their master’s theses in the disciplines of AEEiTK or ITT. The task is to write a short essay by each student on the hypothetical addition of a narrowly applicable QIT layer to the actual implementation of the thesis, if possible. In most cases, this is possible because QITs cover a very wide range of potential technical applications. Where this is not possible, or in the case of an undefined thesis topic, students should write a more general essay or write their personal opinion on what they think about the future of QIT. The current article is another part of a series of works on this topic with subsequent student groups.

Quantum information technologies QIT have two separate but entangled layers - material and ideological. Material layer embraces algorithms, physical devices and systems. Cognitive layer is related to the boundaries and structure of our knowledge, including the magic of nonlocal interactions and subtleties of contextuality. The paradox is that QIT should use quantum magic as a resource to turn into functional utility. The International Year of Quantum Science and Technology is celebrated in Europe, Poland and elsewhere. Opening conference at the UNESCO headquarters in Paris was attended by representatives of the Polish Ministry of Science and Higher Education, and some quantum science groups. Several scientific conferences organized in Poland were announced to the IYQ25 calendar, including: May Symposia of Information and Quantum Horizons in Gdańsk, August Max Born Optical Symposium in Wrocław, September Congress of the Polish Physicists in Katowice. Quantum research projects are realized in Poland, QuantERA, tasks included in the European Quantum Flagship EQF, construction of quantum equipment by university consortia MIKOK, quantum networks and others.

The advanced Quantum Information Technologies subject for Ph.D. students in Electronics Engineering and ICT consists of three parts. A few review lectures concentrate on topics which may be of interest for the students due to their fields of research done individually in their theses. The lectures indicate the diversity of the QIT field, resting on physics and applied mathematics, but possessing wide application range in quantum computing, communications and metrology. The individual IQT seminars prepared by Ph.D. students are as closely related to their real theses as possible. Important part of the seminar is a discussion among the students. The task was to enrich, possibly with a quantum layer, the current research efforts in ICT. And to imagine, what value such a quantum enrichment adds to the research. The result is sometimes astonishing, especially in such cases when quantum layer may be functionally deeply embedded. The final part was to write a short paragraph to a common paper related to individual quantum layer addition to the own research. The paper presents some results of such experiment and is a continuation of previous papers of the same style.

The advancement of quantum computing and artificial intelligence (AI) has presented new challenges and opportunities in cybersecurity. This study compares the effectiveness of Quantum-Enhanced AI and Traditional AI in dealing with cyber threats, especially in terms of computing power, encryption, threat detection, and strategic applications. The research uses literature analysis from 25 significant studies on AI-based cybersecurity and quantum technology. The analysis results show that Quantum-Enhanced AI has significant advantages in faster data processing, Quantum Key Distribution (QKD)-based encryption, and real-time threat detection. This technology is also more adaptive to generative AI attacks and more efficient in securing IoT systems, financial infrastructure, and drone and satellite communications. However, the main challenges include infrastructure limitations, high implementation costs, and the lack of regulations supporting this technology’s widespread adoption. Considering the benefits and challenges, this study emphasizes the importance of investing in Quantum AI research and developing quantum-based cybersecurity standards. Quantum AI is expected to be the leading solution in dealing with cyber threats in the era of quantum computing.

Postęp obliczeń kwantowych i sztucznej inteligencji (AI) stworzył nowe wyzwania i możliwości w zakresie cyberbezpieczeństwa. W tym badaniu porównano skuteczność sztucznej inteligencji wspomaganej kwantowo i tradycyjnej AI w radzeniu sobie z zagrożeniami cybernetycznymi, zwłaszcza pod względem mocy obliczeniowej, szyfrowania, wykrywania zagrożeń i strategicznych zastosowań. Analizowano literaturę z badań na temat cyberbezpieczeństwa opartego na AI i technologii kwantowej. Wyniki analizy pokazują, że sztuczna inteligencja wspomagana kwantowo ma znaczące zalety w szybszym przetwarzaniu danych, szyfrowaniu opartym na dystrybucji klucza kwantowego (QKD) i wykrywaniu zagrożeń w czasie rzeczywistym. Technologia ta jest również bardziej dostosowana do generatywnych ataków AI i bardziej wydajna w zabezpieczaniu systemów IoT, infrastruktury finansowej oraz komunikacji dronów i satelitarnej. Jednak główne wyzwania obejmują ograniczenia infrastruktury, wysokie koszty wdrożenia i brak przepisów wspierających powszechne przyjęcie tej technologii. Biorąc pod uwagę korzyści i wyzwania, niniejsze badanie podkreśla znaczenie inwestowania w badania nad sztuczną inteligencją kwantową i opracowywania standardów cyberbezpieczeństwa opartych na kwantach. Oczekuje się, że sztuczna inteligencja kwantowa będzie wiodącym rozwiązaniem w radzeniu sobie z zagrożeniami cybernetycznymi w erze komputerów kwantowych.

The successful implementation of a machine-learning (ML) model requires three main components: a training data set, a suitable model architecture, and a suitable training procedure. Given the data set and task, finding an appropriate model might be challenging. AutoML, a branch of ML, focuses on an automatic architecture search – a meta method that aims to remove the need for human interaction with the ML system-design process. The success of ML and the development of quantum computing (QC) in recent years has led to the birth of a new fascinating field called quantum machine learning (QML), which incorporates quantum computers into ML models (among other things). In this paper, we present AQMLator, an auto quantum machine-learning platform that aimsto automatically propose and train the quantum layers of an ML model with minimal input from the user. In this way, data scientists can bypass the entry barrier for QC and use QML. AQMLator uses standard ML libraries, making it easy to introduce into existing ML pipelines.

Potential of quantum machine learning for processing multispectral Earth observation data

art. no. e154279

Quantum computers with hundreds of noisy qubits are already available for the research community. They have the potential to run complex quantum computations well beyond the computational capacity of any classical device. It is natural to ask the question, what application these devices could be useful for? Land use and land cover classification of multispectral Earth observation data collected from the earth observation satellite mission is one such problem that is hard for classical methods due to its unique characteristics. In this work, we compare the performance of several classical machine learning algorithms on the stilted re-labeled dataset of the Copernicus Sentinel-2 mission, when the algorithm has access to projected quantum kernel (PQK) features. We show that the classification accuracy increases drastically when the model has access to PQK features. We then naively study the performance of these algorithms with and without access to PQK features on the original Copernicus Sentinel-2 mission data set. This study provides key evidence that shows the potential of quantum machine learning methods for Earth observation data.

Problem marszrutyzacji (optymalizacji trasy) jest kwintesencją problemu optymalizacji kombinatorycznej w badaniach operacyjnych, który ma głębokie implikacje dla logistyki, zarządzania łańcuchem dostaw i systemów transportowych. Jego celem jest określenie najbardziej efektywnych tras dla floty pojazdów do obsługi grupy klientów, biorąc pod uwagę różnego rodzaju ograniczenie, takie jak pojemność pojazdu, okna czasu dostawy i długość trasy. Skuteczne rozwiązanie problemów marszruty ma kluczowe znaczenie dla minimalizacji kosztów operacyjnych, skrócenia czasu dostaw i łagodzenia wpływu na środowisko. Jednakże złożoność tego typu obliczeń rośnie wykładniczo wraz z liczbą klientów i pojazdów, co sprawia, że znalezienie optymalnych rozwiązań w rozsądnych ramach czasowych dla klasycznych algorytmów staje się wyzwaniem obliczeniowym. Z drugiej strony, obliczenia kwantowe, oferują nowatorski paradygmat rozwiązywania złożonych problemów optymalizacyjnych, takich jak problem marszrutyzacji. W artykule zbadano zastosowanie algorytmów kwantowych do optymalizacji tras pojazdów, koncentrując się na ich potencjale w zakresie przezwyciężania ograniczeń klasycznych metod w obsłudze eksplozji kombinatorycznej charakterystycznej dla problemów marszrutyzacji. Zaproponowano podejście hybrydowe, łączące algorytm przybliżonej optymalizacji kwantowej z algorytmem optymalizacji za pomocą roju cząstek. Analizowano zagadnienie związane z wyznaczeniem optymalnych tras pojazdów, które miały obsłużyć 250 klientów. W implementacji kwantowego algorytmu optymalizacyjnego wykorzystano łącznie 251 kubitów. Uzyskane wyniki pokazują, że przy wykorzystaniu metod hybrydowych można skutecznie planować trasy pojazdów.

The vehicle routing problem (VRP) is a quintessential combinatorial optimization problem in operations research that has profound implications for logistics, supply chain management, and transportation systems. Its goal is to determine the most efficient routes for a fleet of vehicles to serve a group of customers, considering various constraints such as vehicle capacity, delivery time windows, and route length. Effectively solving VRP is crucial to minimizing operational costs, reducing delivery times, and mitigating environmental impacts. However, the complexity of this type of computation increases exponentially with the number of customers and vehicles, which makes finding optimal solutions within a reasonable time frame for classical algorithms a computational challenge. On the other hand, quantum computing (QC) offers a novel paradigm for solving complex optimization problems, such as the routing problem. In this paper, the QC application for vehicle route optimization, with a special emphasis on their potential to overcome the limitations of classical methods in handling the combinatorial explosion VRP characteristic has been studied. A hybrid approach was proposed combining an approximate quantum optimization algorithm with a particle swarm optimization algorithm. The problem of determining optimal vehicle routes to serve 250 customers was analyzed. A total of 251 qubits were used to implement the quantum optimization algorithm. The results obtained show that vehicle routes can be effectively planned using hybrid methods.

The aim of the paper is to show how graduated engineering students in classical ICT view practically the advent of the QIT. The students do their theses in El.Eng. and ICT and were asked how to implement now or in the future the QIT in their current or future work. Most of them have strictly defined research topics and in some cases the realization stage is advanced. Thus, most of the potential QIT application areas are defined and quite narrow. In such a case, the issue to be considered is the incorporation of QIT components and interfaces into the existing ICT infrastructure, software and hardware alike, and propose a solution as a reasonable functional hybrid system. The QIT components or circuits are not standalone in most cases, they should be somehow incorporated into existing environment, with a measurable added value. Not an easy task indeed. We have to excuse the students if the proposed solutions are not ripe enough. The exercise was proposed as an on-purpose publication workshop, related strictly to the fast and fascinating development of the QIT. The paper is a continuation of publishing exercises with previous groups of students participating in QIT lectures.

The article is part of a course on Quantum Information Technologies QIT conducted at the Faculty of Electronics and Information Technology of the Warsaw University of Technology. The subject includes a publishing workshop exercised by engineering students. How do ICT engineers see QIT from their point of view? How can they implement quantum technologies in their future work? M.Sc. students usually have strictly declared topics for their master’s theses. The implementation of some works is at an advanced stage. The potential areas of application of QIT are defined and narrow if they are to intellectually expand the area of the completed theses. This is the idea of incorporating QIT components or interfaces into classic ICT solutions at the software and hardware level. It is possible to propose a solution in the form of a functional hybrid system. QIT systems should be functionally incorporated into the existing ICT environment, generating measurable added value. Such a task is quite demanding, but practice shows that it interests students. Solutions don’t have to be mature or even feasible. They can be dreams of young engineers. The exercise is a publication workshop related to the fast development of QIT. The article is a continuation of publication exercises conducted with previous groups of students participating in QIT lectures.

In this study, we introduce a procedural generation technique for Identity Templates applicable to quantum and reversible logic circuits. These templates are recognized for their significant role in enhancing the efficiency of quantum and reversible logic optimization. Our approach enables the exhaustive synthesis of all potential templates up to a specified size. Leveraging the power of SAT-solver technology, we have verified the comprehensiveness of our template collections by confirming the full exploration of the search space. Additionally, we propose an innovative concept of Suboptimality Witnesses, which we anticipate will be instrumental in streamlining the search process in formal methods, akin to SAT-solvers, for the synthesis of reversible logic circuits.

Many real-world problems are dynamic optimization problems that are un-known before hand. In practice, unpredict able events such as the arrival of new jobs, due date changes, and reservation cancellations, changes in parameters or constraints make the search environment dynamic. Many algorithms are designed to deal with stationary optimization problems, but these algorithms do not face dynamic optimization problems or manage them correctly. Although some optimization algorithms are proposed to deal with the changes in dynamic environments differently, there are still areas of improvement in existing algorithms due to limitations or drawbacks, especially in terms of locating and following the previously identified optima. With this in mind, westudied a variant of SSA known as QSSO, which integrates the principles of quantum computing. An attempt is made to improve the overall performance of standard SSA to deal with the dynamic environment effectively by locating and tracking the global optima for DOPs. This work is an extension of the proposed new algorithm QSSO, known as the Quantum-inspired Chaotic SalpSwarm Optimization (QCSSO) Algorithm, which details the various approaches considered while solving DOPs. A chaotic operator is employed with quantum computing to respond to change and guarantee to increase individual searcha-bility by improving population diversity and the speed at which the algorithm converges. We experimented by evaluating QCSSO on a well-known generalized dynamic benchmark problem (GDBG) provided for CEC 2009, followed by a comparative numerical study with well-regarded algorithms. As promised, the introduced QCSSO is discovered as the rival algorithm for DOPs.

Kwantowy kanał informacyjny i proces transmisji w nim informacji klasycznej i kwantowej jest rodzajem operacji kwantowej, analogicznej do tej która jest wykonywana w systemach komputingu kwantowego. W obu przypadkach fundamentem są zasoby kwantowe. Operacje kwantowe w warunkach rzeczywistych podlegają zakłóceniom wynikłym z istnienia wybiórczych kanałów dekoherencji i sprzężenia świata kwantowego z termodynamicznym środowiskiem makro. Stąd, tak chętnie techniki kwantowe korzystają z fotonów, ponieważ są one stosunkowo odporne na dekoherencję. Jedną z najbardziej obiecujących opcji budowy homogenicznych systemów kwantowych obejmujących komputing i teleinformatykę stanowi fotonika kwantowa, odmienna od fotoniki klasycznej. Nie jest to jednak obecnie metoda najprostsza. Na drodze realizacji takiego homogenicznego systemu konieczne są bada- nia, testy, innowacje i budowa funkcjonalnych urządzeń, systemów i aplikacji zapewniających odpowiedni poziom cyberbezpieczeństwa kwantowego. Przestawienie opcji rozwoju telekomunikacji i komputingu na kwanty wymaga koordynacji na poziomie globalnym, tutaj mówimy o poziomie europejskim, dużych programów badawczych, projektów wspomagających kluczowe kierunki rozwojowe, współdziałania z inicjatywami krajowymi i biznesowymi.

Quantum Information Technologies QIT include quantum computing, quantum telecommunications, quantum metrology and synchronization. These areas are closely related to each other because they are based on one common foundation of quantum phenomena. The quantum information channel and the process of transmission of classical and quantum information in it is a kind of quantum operation, analogous to the one performed in quantum computing systems. In both cases, quantum resources are the foundation. Quantum operations in real conditions are subject to disturbances resulting from the existence of selective decoherence channels and the coupling of the quantum world with the thermodynamic macro environment. Hence, quantum techniques are so eager to use photons, because they are relatively resistant to decoherence. One of the most promising options for building homogeneous quantum systems involving computing and QIT is quantum photonics, which is different from classical photon- ics. However, this is currently not the simplest method. On the way to the implementation of such a homogeneous system, research, tests, innovations and the construction of functional devices, systems and applications ensuring an appropriate level of quantum cybersecurity are necessary. Switching telecommunications and computing development options to quanta requires coordination at the global level, here we are talking about the European level, large research programs, projects supporting key development directions, cooperation with national and business initiatives.
