Vulnerability of Satellite Quantum Key Distribution to Disruption from Ground-Based Lasers
Satellite-mediated quantum key distribution (QKD) is set to become a critical technology for quantum-secure communication over long distances. While satellite QKD cannot be effectively eavesdropped, we show it can be disrupted (or ‘jammed’) with ...
