Optical Hybrid-based Optimal Receiver Design for Entanglement-Assisted Communication
Rahul Kumar Bhadani, Ivan B. Djordjević
Abstract
We propose an optical hybrid (OH) based receiver to discriminate phase-shift-keying modulated information that is transmitted using entanglement-assisted (EA) communication. Our numerical result demonstrates that OH-based receivers perform 10% better in terms of error probability and approximately 50% in terms of Shannon’s capacity compared to the previously proposed receiver design.
