Sinara is a modular, open-source measurement and control hardware ecosystem designed for beam-steering and quantum information processing applications that require deterministic high-precision timing. The Sinara system is based on industrial standards and comprises over 70 digital and analog input and output modules. The hardware is controlled and managed by ARTIQ, an open-source software system for experimental control that provides nanosecond timing resolution and sub-microsecond latency via a high-level programming language.

Sinara to modułowa, typu „open-source”, platforma sprzętowo-programistyczna do pomiarów i kontroli, zaprojektowana dla zastosowań w akceleratorach cząstek i przetwarzaniu informacji kwantowej, które wymagają deterministycznego, precyzyjnego timingu. System Sinara opiera się na standardach przemysłowych i składa się z ponad 70 modułów cyfrowych i analogowych wejść i wyjść. Sprzęt jest kontrolowany i zarządzany przez ARTIQ, open-source’owe oprogramowanie do kontroli eksperymentów, które zapewnia rozdzielczość timingu na poziomie nanosekund i latencję w sub-mikrosekundach za pośrednictwem języka programowania wysokiego poziomu.

According to the scaling laws for nanomechanical resonators, many of their metrological properties improve when downscaled. This fact encourages for constant miniaturization of MEMS/NEMS based sensors. It is a well known fact, that the laws of classical physics cannot be used to describe the systems which are arbitrarily small. In consequence, the classical description of nanoresonators must break down for sufficiently small and cool systems and then the quantum effects cannot be neglected. One of the fundamental question which arises is, how one may investigate quantum effects in MEMS/NEMS sensors and what is the influence of quantum effects on the performance of such systems. In this paper we would like to raise those issues by presenting the results of our work related to our estimations and calculations of MEMS/NEMS dynamics. The first and second sections are of theoretical character. In the first section (Classical modeling), we describe the classical methods for describing the resonator dynamics and the classical limit on the resolution of MEMS/NEMS based force sensors, which is set by the thermomechanical noise. In the second section (Quantum aspects), we concentrate on the quantum description of micro and nanoresonators and the influence of quantum effects, such as zero-point motion and back-action, on their performance (quantum limits). The third section is devoted to the presentation of our experimental methods of MEMS/NEMS deflection metrology, i.e. Optical Beam Deflection method (OBD) and fibre optics interferometry.

Nano-particles consisting of a core surrounded by multiple outer shells (multi-shell particles) are used as novel functional materials as well as stiffeners/toughners in conventional composites and nanocomposites. In these heterogeneous particles, the mismatch of thermal expansion coefficients and lattice constants between neighboring shells induces stress/strain fields in the core and shells, which in turn affect the physical/mechanical properties of the particles themselves and/or of the composites containing them. In this paper, we solve the elastostatic inhomogeneous indusion problem of an infinite medium containing a multi-shell spherical particle when the eigenstrains are prescribed in the particle and in the multi-shells, and the inhomogeneity problem when an arbitrary remote stress field is applied to the infinite medium. The corresponding Eshelby and stress concentration tensors of the two problems are obtained and specialised to inhomogeneous inclusions in finite spherical domains with fixed displacement or traction-free boundary conditions. Finally, the Eshelby tensor of a spherical inhomogeneity with non-uniform eigenstrain is obtained and applied to quantum dots of uniform and non-uniform compositions.
