Controlling the photon number coherence of solid-state quantum light sources for quantum cryptography

Controlling the photon number coherence of solid-state quantum light sources for quantum cryptography

Abstract Quantum communication networks rely on quantum cryptographic protocols including quantum key distribution (QKD) based on single photons. A critical element regarding the security of QKD protocols is the photon number coherence (PNC), i.e., the phase relation between the vacuum and one-photo...
