“Nature isn’t classical... and if you want to make a simulation of nature, you’d better make it quantum mechanical...”

Richard P. Feynman

Quantum mechanics is a fundamental theory that describes the properties of the nature at the atomic scale. Recently development of the quantum systems has become a demanded and distinct growing disciplines in technology fields worldwide. They form a platform of a quantum ecosystem, where computers, networks, and sensors as a quantum systems exchange information in a basically new manner by exploiting quantum bits (instead of classical bits) and exchanging them being hundred of kilometers apart from each other. However, development of corresponding cutting edge technologies face unprecedented challenges. Specifically, as devices reach the atomic scale where Quantum Mechanics laws become the driver while laws of classical physics stop governing. Hence, there is strong need of new quantum systems with their control and measurements technologies, which will pave the paths for exploitation of advantages of Quantum Sensing, Quantum Computing, Quantum Communication, Quantum Information Science and Quantum Decision Making for real-world problems. The task itself extremely complicate considering sometimes counterintuitive nature of the quantum mechanics laws and debatable conclusions, which are sometimes lacking empirical confirmations.
