Fast single-photon detectors and real-time key distillation enable high secret-key-rate quantum key distribution systems [PDF]
Nature Photonics, 2022 Quantum key distribution has emerged as the most viable scheme to guarantee information security in the presence of large-scale quantum computers and, thanks to the continuous progress made in the past 20 years, it is now commercially available. However,

Twin-field quantum key distribution without optical frequency dissemination [PDF]
Nature Communications, 2022 Twin-field (TF) quantum key distribution (QKD) has rapidly risen as the most viable solution to long-distance secure fibre communication thanks to its fundamentally repeater-like rate-loss scaling.

Fully Passive Quantum Key Distribution
Physical Review Letters, 2023 Passive implementations of quantum key distribution (QKD) sources are highly desirable as they eliminate side-channels that active modulators might introduce. Up till now, passive decoy-state and passive encoding BB84 schemes have both been proposed.

Practical continuous-variable quantum key distribution with composable security [PDF]
Nature Communications, 2021 A quantum key distribution (QKD) system must fulfill the requirement of universal composability to ensure that any cryptographic application (using the QKD system) is also secure.
