Advances in device-independent quantum key distribution [PDF]
npj Quantum Information, 2022 Device-independent quantum key distribution (DI-QKD) provides the gold standard for secure key exchange. Not only does it allow for information-theoretic security based on quantum mechanics, but it also relaxes the need to physically model the devices ...

Experimental Demonstration of Fully Passive Quantum Key Distribution. [PDF]
Physical Review Letters, 2023 The passive approach to quantum key distribution (QKD) consists of removing all active modulation from the users' devices, a highly desirable countermeasure to get rid of modulator side channels.

Finite key performance of satellite quantum key distribution under practical constraints [PDF]
Communications Physics, 2023 Global-scale quantum communication networks will require efficient long-distance distribution of quantum signals. While optical fibre communications are range-limited due to exponential losses in the absence of quantum memories and repeaters, satellites ...

Lightweight Authentication for Quantum Key Distribution [PDF]
IEEE 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.

Quantum and Semi–Quantum key Distribution in Networks
International 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
