Proposed in 1984, quantum key distribution (QKD) allows two users to exchange provably
secure keys via a potentially insecure quantum channel. Since then, QKD has attracted …

Distributing secret keys with information-theoretic security is arguably one of the most
important achievements of the field of quantum information processing and communications …

Quantum key distribution (QKD) is a quantum communication technology that promises
unconditional communication security. High-performance and cost-effective QKD systems …

Quantum key distribution provides secure keys resistant to code-breaking quantum
computers. The continuous-variable version of quantum key distribution offers the …

We report on what we believe is the first field implementation of a continuous-variable
quantum key distribution (CV-QKD) network with point-to-point configuration. Four QKD …

Quantum key distribution (QKD) provides a promising solution for sharing information-
theoretic secure keys between remote peers with physics-based protocols. According to the …

Measurement-device-independent quantum key distribution (MDI-QKD) can remove all side-
channel attacks on detectors. In the context of the dramatic progress of discrete-variable MDI …

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 …

Quantum key distribution (QKD) uniquely allows the distribution of cryptographic keys with
security verified by quantum mechanical limits. Both protocol execution and subsequent …

Use of low-noise detectors can both increase the secret bit rate of long-distance quantum
key distribution (QKD) and dramatically extend the length of a fibre optic link over which …
