Ultimate accuracy limit of quantum pulse-compression ranging

2021 · Quantum Information and Measurement VI 2021

We establish microwave-radar ranging's ultimate quantum limit, and show that quantum illumination (QI) ranging achieves this limit. Moreover, QI's ranging accuracy can be 10's of dB better than that of its best classical competitor.

Performance analysis for high-dimensional Bell-state quantum illumination

2024 · arXiv (Cornell University)

Quantum illumination (QI) is an entanglement-based protocol for improving lidar/radar detection of unresolved targets beyond what a classical lidar/radar of the same average transmitted energy can do. Originally proposed by Lloyd as a discrete-variable quantum …
