The article is a sort of advanced publication workshop prepared by a group of M.Sc. students in ICT participating in the course on QIT. The idea behind the publishing exercise is to try to link, if possible, individual own work just under realization for the thesis with new unique possibilities offered by the QIT. Each chapter is written by a single author defining concisely her/his research interest in the classical ICT field and trying to find possible correlations with respective abruptly developing branches of the QIT. The chapter texts are somehow moderated by the tutor but are exclusively authored by young researchers. The aim was to present their views on the possible development directions of particular subfields of QIT, if not fully mature, but still based on their own ideas, research and dreams.

This article discusses four fields of study with the potential to revolutionize our understanding and interaction with biological systems: quantum biophotonics, molecular and supramolecular bioelectronics, quantum-based approaches in gaming, and nano-biophotonics. Quantum biophotonics uses photonics, biochemistry, biophysics, and quantum information technologies to study biological systems at the sub-nanoscale level. Molecular and supramolecular bioelectronics aim to develop biosensors for medical diagnosis, environmental monitoring, and food safety by designing materials and devices that interface with biological systems at the molecular level. Quantum-based approaches in gaming improve modeling of complex systems, while nanomedicine enhances disease diagnosis, treatment, and prevention using nanoscale devices and sensors developed with quantum biophotonics. Lastly, nano-biophotonics studies cellular structures and functions with unprecedented resolution.

QIT–Quantum Information Technologies promises are very serious, greatly exceeding only technical and market levels. Development of QIT in Europe, treated as building a new infrastructural civilization level, requires a broader view of coordination, funding and priority-setting policy. Simple measures used in the case of the development of new technologies, but not creating a significant ecosystem, are insufficient in this case. Quantum technologies are poised to create a new information layer of knowledge-based society. In this essay, the author subjectively addresses some of the issues such as: what we already know and what we don't know, and what efforts are being made in Europe. Polish version of this paper was published in Przegl.Telekom.2.23.

Europe has to face strong competitive challenges in the field of QIT from other regions of the world. The tools for the effective implementation of the challenges related to the start, we hope, of building a quantum civilization are both common and individual in particular European countries. Joint projects in the field of QIT, usually narrowly focused, are announced by large European Agencies and are related to their activities. Large-scale collaborative projects are of course the domain of the EC. National projects depend heavily on the capabilities of individual countries and vary greatly in size. The most technologically advanced European countries invest hundreds of millions of Euros in national QIT projects annually. The largest European FET class project currently being implemented is the Quantum Flagship. Although the EQF is basically just one of the elements of a large and complicated European scene of development of quantum technologies, it becomes the most important element and, in a sense, a dominant one, also supported from the political level. There are complex connections and feedbacks between the elements of this quantum scene. National projects try to link to the EQF. Here we are interested in such connections and their impact on the effectiveness of QIT development in Europe, and especially in Poland.

Informacyjne techniki kwantowe obejmują obok komputingu kwantowego także obrazowanie kwantowe (OK). Obrazowanie kwantowe jest jednocześnie fragmentem optyki kwantowej. Podobnie do obrazowania klasycznego, obrazowanie kwantowe jest procesem który zawiera warstwę sprzętową, po stronie nadawczej i odbiorczej, i warstwę programistyczną, jak akwizycji obrazu, czyli np. oświetlenia/prześwietlenia lub nie obiektu, identyfikacji scenerii, detekcji odpowiedniego fragmentu sceny, zapisu danych, transmisji danych, przetwarzania. Większość z tych elementów procesu obrazowania może mieć charakter kwantowy. Jeśli scena jest oświetlona to światło może być nieklasyczne kwantowe, sub-Poissonowskie. Scenę można oświetlać także deterministycznymi pojedynczymi fotonami lub parą fotonów splątanych z zastosowaniem techniki fotonu zwiastowanego. Po stronie odbiorczej w obrazowaniu kwantowym można stosować fotodetektory i kamery jednofotonowe. Kwantowe dwufotonowe obrazowanie koincydencyjne tworzy obraz przez łączenie informacji z dwóch detektorów: wysokorozdzielczej matrycy CCD nie obserwującej obiektu i jednopikselowego detektora obserwującego obiekt. Para splątanych fotonów jest detekowana przez oba detektory jednocześnie. Jeden foton z pary, sygnałowy, pada na obiekt, oddziałuje z nim, i następnie jest rejestrowany przez detektor jednopikselowy. Drugi foton pary, zwiastowany, podąża inną drogą optyczną do detektora CCD. Klasyczna metoda obrazowania koincydencyjnego używa skorelowanych wiązek koherentnych bez wykorzystania splątania fotonów. Korelacyjne obrazowanie kwantowe redukuje SNR. W kwantowym obrazowaniu fluorescencyjnym, a także z zastosowaniem fali materialnej de Broglie np. z atomami He, możliwe jest obejście klasycznego ograniczenia Rayleigha-Abbego rozdzielczości obrazu optycznego tylko do 200 nm. Osiągane rozdzielczości obrazowania kwantowego są na poziomie pojedynczych nm.

Quantum information techniques include, aside from quantum computing, also quantum imaging (QI). Quantum imaging is also a part of quantum optics. Similar to classical imaging, quantum imaging is a process that includes a hardware layer, on the transmitting and receiving side, and programmatic layer like: image acquisition, i.e. lighting/trans illumination of an object, identification of the scenery, detection of the appropriate part of the scene, data recording, data transmission, processing. Most of these elements of the imaging process can be quantum in nature. If the stage is lit, the light may be non-classical quantum, sub-Poissonian. The scene can also be illuminated with deterministic single photons or a pair of entangled photons using the heralded photon technique. On the receiving side, in quantum imaging, photodetectors and single-photon cameras can be used. Quantum two-photon coincidence imaging (ghost imaging) creates an image by combining information from two detectors: a high-resolution CCD not observing the object and one-pixel detector that observes the object. A pair of entangled photons is detected by both detectors simultaneously. One photon from the pair, the signal photon, falls on the object and is then registered by a one-pixel detector. The second photon of the pair, heralded, follows a different optical path to the CCD detector. The classical method of coincidence imaging uses correlated coherent beams without the use of photon entanglement. Correlational quantum imaging reduces the SNR. In quantum fluorescence imaging, as well as using de Broglie material waves with Helium atoms, it is possible to circumvent the classic Rayleigh-Abbe limitation of the optical image resolution to 200 nm. The obtainable resolutions of quantum imaging reach the level of single nm.

Biofotonika jest dziedziną na pograniczu biologii i fotoniki. Jest obszarem badawczym i aplikacyjnym obejmującym zjawiska i procesy, substancje, obiekty w skali rozmiarowej od nanometrów do makro, jak wirusy, molekuły, organella, komórki, bakterie, membrany, tkanki, małe i większe organizmy, w aspekcie ich właściwości fotonicznych. Biofotonika obejmuje oprzyrządowanie laboratoryjne badawcze i standaryzowane kliniczne i ogólnego zastosowania. Aktywnym kierunkiem rozwoju biofotoniki jest jej gałąź kwantowa, gdzie badane są procesy zachodzące na ogół w nanoskali. Zainteresowanie tymi nanoprocesami, albo zawierającymi zjawisko fotoniczne, albo badane metodami fotonicznymi, bierze się z faktu że stanowią one często fundament procesów zachodzących i odzwierciedlanych potem w makroskali całego obiektu biologicznego. Cykl artykułów na temat biofotoniki jest skrótem wykładu prowadzonego przez autora na WEiTI Politechniki Warszawskiej dla doktorantów. Kolejna część cyklu dotyczy obrazowania wysoko rozdzielczego, poniżej limitu dyfrakcyjnego Abbego. Poprzednie części dotyczyły obszarów badawczych i korelacji biofotoniki z pokrewnymi dyscyplinami, procesów biofotonicznych, foto-biosubstancji, obiektów, spektroskopii, biofotonicznych technik laboratoryjnych.

Biophotonics is a field on the border of biology and photonics. It is a research and application area covering phenomena and processes, substances, objects in the size scale from nanometers to macro, such as viruses, molecules, organelles, cells, bacteria, membranes, tissues, small and larger organisms, in terms of their photonic properties. Biophotonics includes research and standardized clinical and general-purpose laboratory instrumentation. An active direction in the development of biophotonics is its quantum branch, where processes that usually occur at the nanoscale are studied. The interest in these nanoprocesses, either containing a photonic phenomenon or studied with photonic methods, stems from the fact that they often constitute the foundation of processes that occur and are later reflected in the macroscale of the entire biological object. The series of articles on biophotonics is an abbreviation of a lecture given by the author at the Faculty of Economics and Information Technology of the Warsaw University of Technology for PhD students. The next part of the series deals with the issues of super-resolution imaging, breaking the Abbe diffraction limit. The previous parts concerned research areas and correlations of biophotonics with related disciplines, biophotonic processes, photo-biosubstances, objects, spectroscopy, biophotonic laboratory techniques.

Technologia kwantowa jest obszarem coraz skuteczniej funkcjonalizującym zjawiska mechaniki kwantowej, nie tylko jak to robiono dotychczas z sukcesem, czyli głównie poprzez inżynierię przerwy zabronionej. Epoka Quantum-1 dała nam układy scalone, lasery, czujniki, komputery, informatykę, telekomunikację światłowodową i satelitarną. W wielu obszarach Quantum-1 doszliśmy, lub za jakiś czas dojdziemy, do granic technologicznych. Świat naukowy zauważył możliwość dalszego, nie ewolucyjnego, ale skokowego rozwoju wymienionych technologii poprzez zmianę epoki na coś co dzisiaj nazywamy Quantum 2. Quantum 2 nie bazuje na przerwie zabronionej tak jak Quantum 1, ale usiłuje dowolnie manipulować pojedynczym izolowanym, a także grupą skorelowanych układów kwantowych. Za taką datę narodzin Quantum 2 uznaje się odkrycie przez Johna Stewarda Bella w 1964 roku nierówności i sformułowanie na jej podstawie prawa dotyczącego ścisłej granicy nielokalności kwantowej w układzie dwustronnym, lub jak dzisiaj mówimy dowodu splątania między Alicją i Bobem. J.S.Bell przedstawił możliwość prostej i ścisłej eksperymentalnej weryfikacji paradoksu EPR z roku 1934 poprzez statystyczny pomiar korelacji kwantowych. Nie od razu skonsumowano to genialne odkrycie. Pierwszy prosty eksperyment weryfikacyjny prawdziwość naruszenie nierówności wykonał zespół Johna Clausera w r. 1979 na podstawie wyprowadzonej w roku 1969 nierówności klasy Bella - CHSH. Pełny eksperyment, jednak bez unikania większości luk pomiarowych, wykonał po raz pierwszy zespół Alaina Aspecta w roku 1982. Zespół Antona Zeilingera wykonał wiele testów Bella także w skali kosmicznej, pokazał pierwszy teleportację kwantową i możliwość manipulacji splątaniem poprzez jego przełączanie między kubitami. Clauser, Aspect i Zeilinger otrzymali nagrodę Nobla z fizyki za te osiągnięcia w roku 2022. Stanowią one bramę wejściową do epoki Quantum 2 i podstawę rozwoju informacyjnych technologii kwantowych na fizycznej platformie fotoniki kwantowej.

Quantum technology is an area that is increasingly functionalizing the phenomena of quantum mechanics, not only as it has been successfully done so far, i.e. mainly through the forbidden gap engineering. The Quantum-1 era gave us integrated circuits, lasers, sensors, computers, IT, fiber optic and satellite telecommunications. In many areas of Quantum-1, we have reached or will come to technological limits in some time. The scientific world has noticed the possibility of a further, not evolutionary, but leapfrog development of these technologies by changing the epoch to what we now call Quantum-2. Quantum-2 is not based on a forbidden band like Quantum-1, but tries to arbitrarily manipulate a single isolated as well as a group of correlated quantum systems. The birth date of Quantum-2 is considered to be the discovery by John Steward Bell in 1964 of inequality and the formulation of a law on the strict limit of quantum nonlocality in a bilateral system, or as we speak today, the proof of entanglement between Alice and Bob. J.S.Bell presented the possibility of a simple and strict experimental verification of the EPR paradox from 1934 through the statistical measurement of quantum correlations. This brilliant discovery was not immediately consumed. The first simple experiment to verify the truth of the inequality was performed by John Clauser’s team in 1979 on the basis of the Bell-class CHSH inequality derived in 1969. The full experiment, but without avoiding all measurement loopholes, was first performed by Alain Aspect’s team in 1982. Anton Zeilinger’s team performed many Bell tests also on a cosmic scale, showed the first quantum teleportation and the possibility of manipulating entanglement by switching between qubits. Clauser, Aspect and Zeilinger were awarded the Nobel Prize in Physics for these achievements in 2022. They are the gateway to the Quantum-2 era and the basis for the development of quantum information technologies on the physical quantum photonics platform.

CERN hosted on May 2-6, 2022, the first annual meeting of the H2020 I.FAST project to support innovation in the field of science and technology of particle accelerators. The project has a completely different character from its predecessors in this area of research. It was approved for implementation a year ago by the EC with the highest marks. It is worth looking at why projects such as ARIES, I.FAST and EURO-LABS are so easily accepted. This alleged ease of acceptance is an appearance. Behind the acceptance, in conditions of extremely tough competition, is the excellent organization of the submitting community that has been developed over the years, as well as the perfect, well-thought-out preparation of the material. The author, a participant in the ARIES and other EC projects in the field of particle accelerator science and technology, presents here, on specific examples, his subjective opinions on how to prepare materials for high-output projects for the EC FP. The author hopes that these remarks may be useful in the process of submitting research projects from Poland in international cooperation to the EC in the best possible way. The science and technology of particle accelerators is an excellent area of showing such examples because it is interdisciplinary and includes the following components: building of research infrastructure, applied physics, mechatronics, materials engineering, automation and robotics, electronics, ICT, innovation, cooperation with industry, and social.

Ustanowienie przez Organizację Narodów Zjednoczonych Międzynarodowego Roku Szkła 2022 zwraca uwagę nie tylko na ten wspaniały i różnorodny materiał, ale także na jego uwarunkowania i role kulturowe, historyczne, cywilizacyjne, a dla nas czytelników Elektroniki naukowo-techniczne i przemysłowe. MR Szkła, jak przyznają jego organizatorzy, jest w pewnym sensie kontynuacją bardzo udanego Międzynarodowego Roku Światła 2015. Bez sukcesu MRŚ2015 prawdopodobnie nie byłby możliwy MRS2022? Szkło jest podstawą inżynierii optycznej, optyki objętościowej, a także w dużej mierze optyki scalonej i zintegrowanej. Szkło krzemionkowe syntetyzowane z fazy gazowej stanowi fundament telekomunikacji światłowodowej. Znaczne postępy w badaniach i zastosowaniach szkieł dla technologii ICT umożliwiły takie narzędzia jak lasery femtosekundowe i nanometrowa obróbka materiałów. Szklane nanometrowe struktury periodyczne, a w przyszłości periodyczne modulowane, otwarły możliwości kształtowania struktury falowej pojedynczego fotonu. Napotykając na takie bezstratne struktury szklane o wymiarach atomowych funkcja falowa fotonu oddziałuje z ich falą materialną De Broglie. W rezultacie oddziaływania funkcja falowa fotonu zawiera składniki pochodzące od fali materialnej. Foton ubieramy w stacjonarnie materialny płaszcz. Szkło ma niezwykłą przyszłość w optycznych fotonowych liniowych realizacjach procesorów i urządzeń funkcjonalnych kwantowych technik informacyjnych.

The establishment by the United Nations of the International Year of Glass 2022 draws attention not only to this wonderful and diverse material, but also to its cultural, historical, civilization aspects and roles, and for us, the readers of the Journal Elektronika also the roles in science, technology and industry. The International Year of Glass IYoG 2022, as its organizers admit, is in a sense a continuation of the very successful International Year of Light 2015 (IYoL). Without the success of the IYoL2015, the IYoG2022 probably would not be possible at all? Glass is the basis of optical engineering, volume optics, and also largely hybrid and integrated optics. Gas-phase synthesized silica glass is the foundation of fiber optic telecommunications. Tools such as femtosecond lasers and nanometer material processing technologies have enabled significant advances in research and application of glasses for the ICT. Glass nanometer periodic structures, and in the future periodic modulated ones, opened up the possibility of shaping the wave structure of a single photon. When encountering such atomic-sized lossless glass structures, the photon’s wave function interacts with their De Broglie material wave. As a result of the interaction, the photon’s wave function contains components derived from the material wave. We dress the photon in a stationary material mantle. Glass has a remarkable future in optical photon, linear realizations of processors and functional circuits of quantum information techniques.

This article reviews chosen topics related to the development of Information Quantum Technologies in the major areas of measurements, communications, and computing. These fields start to build their ecosystems which in the future will probably coalesce into a homogeneous quantum information layer consisting of such interconnected components as quantum internet, full size quantum computers with efficient error corrections and ultrasensitive quantum metrology nodes stationary and mobile. Today, however, the skepticism expressing many doubts about the realizability of this optimistic view fights with a cheap optimism pouring out of some popular press releases. Where is the truth? Financing of the IQT by key players in research, development and markets substantially strengthens the optimistic side. Keeping the bright side with some reservations, we concentrate on showing the FAST pace of IQT developments in such areas as biological sciences, quantum evolutionary computations, quantum internet and some of its components.

The ILC is an immense e+e- machine planned since 2004 by a large international collaboration, to be potentially built in Japan [1]. The gigantic size of the whole research infrastructure, the involved human, technical and financial resources, and the pressure of new emerging and potentially soon to be competitive accelerator technologies, make the final building decision quite difficult. A vivid debate is carried on this subject globally by involved accelerator research communities. The European voice is very strong and important in this debate, and has recently been essentially refreshed by clear statements in a few official documents [2]. The final HEP European Strategy Document is just under preparation. This paper is a very modest and subjective voice in this debate originating from Poland, which around 50 researchers are present at the list of 2400 signatories for the original ILC TDR document published in 2013 [3].

This article has two outreach aims. It concisely summarizes the main research and technical efforts in the EC H2020 ARIES Integrating Activity – Accelerator Research and Innovation for European Science and Society [1] during the period 2017/2018. ARIES is a continuation of CARE, TIARA and EuCARD projects [2-3]. The article also tries to show these results as an encouragement for local physics and engineering, research and technical communities to participate actively in such important European projects. According to the author’s opinion this participation may be much bigger [4-27]. All the needed components to participate – human, material and infrastructural are there [4,7]. So why the results are not satisfying as they should be? The major research subjects of ARIES are: new methods of particles acceleration including laser, plasma and particle beam interactions, new materials and accelerator components, building new generations of accelerators, energy efficiency and management of large accelerator systems, innovative superconducting magnets, high field and ultra-high gradient magnets, cost lowering, system miniaturization, promotion of innovation originating from accelerator research, industrial applications, and societal implications. Two institutions from Poland participate in ARIES – these are Warsaw University of Technology and Institute of Nuclear Chemistry and Technology in Warsaw. There are not present some of the key institutes active in accelerator technology in Poland. Let this article be a small contribution why Poland, a country of such big research potential, contributes so modestly to the European accelerator infrastructural projects? The article bases on public and internal documents of ARIES project, including the EU Grant Agreement and P1 report. The views presented in the paper are only by the author and not necessarily by the ARIES.
