Sushil Kumar, Soumya P. Dash, George C. Alexandropoulos
A reconfigurable intelligent surface (RIS)-assisted multiple-input multiple-output (MIMO) continuous-variable quantum key distribution (CV-QKD) system operating at terahertz (THz)…
MIMO FSO Systems in Hybrid Quantum Noise Environments: SKR Analysis with One- and Two-way CV-QKD Protocols
Sushil Kumar, Soumya P. Dash, George C. Alexandropoulos
This paper studies a multiple-input multiple-output (MIMO) free-space optical (FSO) communication system employing continuous-variable quantum key distribution (CV-QKD), with the g…
Performance Analysis of One- and Two-way DV-QKD with MIMO FSO Communication Systems
Sushil Kumar, Soumya P. Dash, George C. Alexandropoulos
This paper considers a multiple-input multiple-output (MIMO) wireless system wherein two legitimate users attempt to exchange secret keys over free-space optical (FSO) channels. No…
