Thermal state quantum key distribution [PDF]
Journal of Physics B: Atomic, Molecular and Optical Physics, 2021 Abstract We analyse a central broadcast continuous variable quantum key distribution protocol in which a beam produced by a thermal source is used to create a secret key between two parties, Alice and Bob. A beam splitter divides the initial beam into a pair of output beams, which are sent to Alice and Bob, with Eve intercepting Bob’s ...

Information Reconciliation for High-Dimensional Quantum Key Distribution using Nonbinary LDPC codes [PDF]
, 2023 Information Reconciliation is an essential part of Quantum Key distribution protocols that closely resembles Slepian-Wolf coding. The application of nonbinary LDPC codes in the Information Reconciliation stage of a high-dimensional discrete-variable Quantum Key Distribution setup is proposed.

The Case for Quantum Key Distribution [PDF]
, 2010 Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures. It can provide long-term confidentiality for encrypted information without reliance on computational assumptions. Although QKD still requires authentication to prevent man-

A Review of Security Evaluation of Practical Quantum Key Distribution System
Entropy, 2022 Although the unconditional security of quantum key distribution (QKD) has been widely studied, the imperfections of the practical devices leave potential loopholes for Eve to spy the final key.

Breaking the Rate-Loss Bound of Quantum Key Distribution with Asynchronous Two-Photon Interference [PDF]
PRX Quantum, 2021 Twin-field quantum key distribution can overcome the secret key capacity of repeaterless quantum key distribution via single-photon interference. However, to compensate for the channel fluctuations and lock the laser fluctuations, the techniques of phase ...

Comment on "Quantum Key Distribution with Classical Bob" [PDF]
PRL 102, 098901 (2009), 2009 In this comment, we present a frequency-shift attack on "quantum key distribution with classical Bob". This practical attack should also be considered in other two-way quantum key distribution protocols.

Twin-field quantum key distribution with passive-decoy state
New 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.

Daylight entanglement-based quantum key distribution with a quantum dot source [PDF]
Quantum Science and Technology, 2022 Entanglement-based quantum key distribution can enable secure communication in trusted node-free networks and over long distances. Although implementations exist both in fiber and in free space, the latter approach is often considered challenging due to ...

Quantum key distribution protocol based on contextuality monogamy [PDF]
Phys. Rev. A 95, 062333 (2017), 2016 The security of quantum key distribution protocols hinges upon features of physical systems that are uniquely quantum in nature. We explore the role of quantumness as qualified by quantum contextuality, in quantum key distribution schemes. We present a new quantum key distribution protocol whose security depends uponthe KCBS inequality and ...
