Quantum Key Distribution Networks: Challenges and Future Research Issues in Security
Applied Sciences, 2021 A quantum key distribution (QKD) network is proposed to allow QKD protocols to be the infrastructure of the Internet for distributing unconditional security keys instead of existing public-key cryptography based on computationally complex mathematical ...

Limitations on quantum key repeaters [PDF]
Nature Communications, 2015 A major application of quantum communication is the distribution of entangled particles for use in quantum key distribution (QKD). Due to noise in the communication line, QKD is in practice limited to a distance of a few hundred kilometres, and can only be extended to longer distances by use of a quantum repeater, a device which performs entanglement ...

Device-independent quantum key distribution with asymmetric CHSH inequalities
Quantum, 2021 The simplest device-independent quantum key distribution protocol is based on the Clauser-Horne-Shimony-Holt (CHSH) Bell inequality and allows two users, Alice and Bob, to generate a secret key if they observe sufficiently strong correlations.

Composable security for continuous variable quantum key distribution: Trust levels and practical key rates in wired and wireless networks [PDF]
Physical Review Research, 2021 Continuous variable (CV) quantum key distribution (QKD) provides a powerful setting for secure quantum communications, thanks to the use of room-temperature off-the-shelf optical devices and the potential to reach much higher rates than the standard ...

High-performance cavity-enhanced quantum memory with warm atomic cell
Nature Communications, 2022 Quantum memories usually suffer from a trade-off between efficiency and excess noise. Here, by exploiting the time-reversal approach for improving modes matching, the authors show a warm-atomic-cell-based cavity-enhanced memory with 67% efficiency and ...
