Quantum key distribution (QKD), has the potential to enable secure communication and
information transfer. In the laboratory, the feasibility of point-to-point QKD is evident from the …

Twin-field quantum key distribution can overcome the secret key capacity of repeaterless
quantum key distribution via single-photon interference. However, to compensate for the …

Secure key rate (SKR) of point-point quantum key distribution (QKD) is fundamentally
bounded by the rate-loss limit. Recent breakthrough of twin-field (TF) QKD can overcome …

Quantum key distribution—the establishment of information-theoretically secure keys based
on quantum physics—is mainly limited by its practical performance, which is characterised …

The basic principle of quantum mechanics guarantees the unconditional security of quantum
key distribution (QKD),,,–at the cost of forbidding the amplification of a quantum state. As a …

Twin-field (TF) quantum key distribution (QKD) fundamentally alters the rate-distance
relationship of QKD, offering the scaling of a single-node quantum repeater. Although recent …
