Development of a Receiving Module of a Quantum Receiver for Optimal Discrimination of Coherent Optical States

Student: Tatiana Andriianova

Supervisor: Roman Ozhegov

Faculty: HSE Tikhonov Moscow Institute of Electronics and Mathematics (MIEM HSE)

Educational Programme: Electronic Engineering (Master)

Final Grade: 9

Year of Graduation: 2019

The work is dedicated to the development of a receiving module of a quantum optical receiver for a phase-modulated signal detection. The subject of research is the optimal discrimination of two coherent optical states, i.e. their detection with minimal error. The object of study is represented by a receiving module as part of a quantum receiver, which performs the following functions: • registers voltage pulses from a single photon detector • generates signals applied to the phase shifter • is engaged in processing the data. There was made a review and analysis of receivers’ existing models for coherent optical communication, the electrical circuit of the new receiving module was developed, a printed circuit board was designed, the principle of operation was described, and a feasibility study was carried out.
