Integrated Microwave Quantum Sensing for Radar Type Problems Decisions

The article sets the tasks for multi-sensor systems design, which are acute both in microwave photonics and integrated quantum nets in the problems of one time probing plurality of sensors, its discrimination, localization, and increasing the sensitivity and accuracy of measurements. To solve it, it is supposed, firstly, to use the principles of constructing a unified field of address sensors, and to probe the latter by radiation of comb generators synthesized by Il'in-Morozov's method. Given method consists in generating of two or more “entangled” frequencies based on the amplitude-phase transformation of the optical carrier as in the classical and in the quantum representation - the creation of a pair of entangled photons spaced symmetrically from the suppressed original carrier. Secondly, operations with one-photon fields in realistic conditions is associated with the need to highlight relevant information against the background of inevitably occurring quantum noises, for which static methods of quantum detection and tomography of quantum states have to be used. Thirdly, it is proposed to solve passive and active radar type problems, based on the transfer of few-mode microwave photonics technologies to the field of quantum sensors. For this purpose, system solutions of microwave photonics have to undergo adaptation to integrated platforms in order to create its element base and to use it further for implementing multi-sensor technologies in the integrated quantum field.
