Graphene enables room temperature single photon emitter and detector for unhackable Quantum Key Cryptography (QKD)

Quantum Key Distribution, or QKD, enables two remote parties, “Alice” and “Bob”, who are connected by a passive optical link to securely generate secret key material. Single-photon sources (SPSs) and single-photon detectors (SPDs) are key devices for enabling practical quantum key distributions (QKDs).  Single photon generation is necessary for secure quantum transmission; otherwise, an eavesdropping party might…
