The State of the Art in Satellite Quantum Key Distribution: Protocols, Technologies, and Physical Limits

ABSTRACT This review presents the state of the art in quantum key distribution (QKD) for satellite‐to‐ground free‐space optical links. It first surveys continuous‐variable, discrete‐variable, entanglement‐based, measurement‐device‐independent, and twin‐field protocols, and discus...
