Investigation of Joint Photonic-Electromagnetic resonances between Optical Fibres and Superconducting Circuits to Enhance Quantum Communication

Abstract

Quantum communication networks necessitate effective interfaces between superconducting circuits operating in the microwave regime and optical fibers, thereby facilitating the transmission of optical signals over long distances, this research paper proposes a novel scheme for achieving hybrid , opto-electromagnetic resonances through the use of nanomechanical resonators and electro-optic converters to bridge the frequency gap between microwave and optical frequencies. We present a theory for the coherent conversion of quantum signals, aimed at achieving high precision and low loss. The proposed system integrates superconducting qubits with optical fibers, building upon recent advancements in microwave-to-optical conversion. Simulation results indicate that under optimal conditions, conversion efficiencies of up to 85% can be attained, leading to scalable quantum networks. This work addresses critical issues in quantum communication, such as signal loss and degradation, and showcases practical applications for regional quantum networks.
