Performance Analysis of Free-space Quantum Key Distribution Using Multiple Spatial Modes
Wenhua He, Saikat Guha, Jeffrey H. Shapiro +1
In the diffraction-limited near-field propagation regime, free-space optical quantum key distribution (QKD) systems can employ multiple spatial modes to improve their key rate. Her…
Covert Capacity of Bosonic Channels
Christos N. Gagatsos, Michael S. Bullock, Boulat A. Bash
We investigate the quantum-secure covert-communication capabilities of lossy thermal-noise bosonic channels, the quantum-mechanical model for many practical channels. We determine…
Covert sensing using floodlight illumination
Christos N. Gagatsos, Boulat A. Bash, Animesh Datta +2
We propose a scheme for covert active sensing using floodlight illumination from a THz-bandwidth amplified spontaneous emission (ASE) source and heterodyne detection. We evaluate t…
