Atmospheric Turbulence-Aware Optimization of Generalized Kennedy Receivers for Coherent-State BPSK Quantum Communication
Md Ashraf Hossain Ifty, Rahul Bhadani
We investigate generalized Kennedy receivers for coherent-state BPSK communication over turbulent free-space optical channels. An ergodic mutual-information framework is developed…

Optimized Receiver Design for Entanglement-Assisted Communication using BPSK
Rahul Bhadani, Ivan B. Djordjevic
The use of pre-shared entanglement in entanglement-assisted communication offers a superior alternative to classical communication, especially in the photon-starved regime and high…

Programming the Kennedy Receiver for Capacity Maximization versus Minimizing One-shot Error Probability
Rahul Bhadani, Michael Grace, Ivan B. Djordjevic +2
We find the capacity attained by the Kennedy receiver for coherent-state BPSK when the symbol prior p and pre-detection displacement are optimized. The optimal displacement is diff…
