Quantum Illumination: From Enhanced Target Detection to Gbps Quantum Key Distribution
Jeffrey H. Shapiro · Conference on Lasers and Electro-Optics · 2017
We review theory and experiments for quantum illumination—entanglement-based protocols for enhanced target detection and secure classical communication—and show that its unentangled descendant, floodlight quantum key distribution, affords Gbps secret-key rates over metropolitan-area distances.
