Receiver-device-independent quantum key distribution protocols

open access: yesNew Journal of Physics, 2022
We discuss quantum key distribution protocols and their security analysis, considering a receiver-device-independent (RDI) model. The sender’s (Alice’s) device is partially characterized, in the sense that we assume bounds on the overlaps of the prepared

Lightweight Authentication for Quantum Key Distribution [PDF]

open access: yesIEEE Transactions on Information Theory, 2020
Quantum key distribution (QKD) enables unconditionally secure communication between distinct parties using a quantum channel and an authentic public channel. Reducing the portion of quantum-generated secret keys, that is consumed during the authentication procedure, is of significant importance for improving the performance of QKD systems.

Twin-field quantum key distribution with passive-decoy state

open access: yesNew Journal of Physics, 2020
Twin-Field quantum key distribution (TF-QKD) and its variants, e.g. phase-maching QKD, sending-or-not-sending QKD, and no phase post-selection TFQKD promise high key rates at long distance to beat the rate distance limit without a repeater.

SECURITY OF QUANTUM KEY DISTRIBUTION [PDF]

open access: yesInternational Journal of Quantum Information, 2008
Quantum Information Theory is an area of physics which studies both fundamental and applied issues in quantum mechanics from an information-theoretical viewpoint. The underlying techniques are, however, often restricted to the analysis of systems which satisfy a certain independence condition.

Quantum and Semi–Quantum key Distribution in Networks

open access: yesInternational Journal of Theoretical Physics, 2023
In this paper, we utilize the potential offered by multidimensional separable states (MSS) for secure and simultaneous distributions of keys in a layered network. We present protocols for both quantum and semi-quantum key distribution and discuss their robustness against various eavesdropping strategies. We provide a procedure to identify the requisite

Phase-Matching Quantum Key Distribution

open access: yesPhysical Review X, 2018
Quantum key distribution allows remote parties to generate information-theoretic secure keys. The bottleneck throttling its real-life applications lies in the limited communication distance and key generation speed, due to the fact that the information ...

Practical issues of twin-field quantum key distribution

open access: yesNew Journal of Physics, 2019
Twin-field quantum key distribution(TF-QKD) protocol and its variants, such as phase-matching QKD, sending-or-not-sending QKD and no phase post-selection TF-QKD(NPP-TFQKD), are very promising for long-distance applications.

Fully Passive Quantum Key Distribution

open access: yesPhysical 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.
