Homodyne versus Heterodyne for Quantum Measurement

Homodyne versus Heterodyne for Quantum Measurement

연구 분야: Cryptography

학회: ReAQCT '24: Proceedings of Recent Advances in Quantum Computing and Technology

In this paper, we study two well-characterized continuous variable detections, homodyne and heterodyne, and then compare their performance in phase keying or amplitude modulation schemes where indistinguishable states are being measured. We compare their performance in terms of generation rate and amount of extractable information necessary for quantum secure applications.
