Free‐Space Time‐Bin Encoded Quantum Key Distribution from Near‐ to Mid‐Infrared Wavelengths

Advanced Quantum Technologies, Volume 9, Issue 4, April 2026.
This work investigates free‐space communication based on quantum key distribution (QKD) in the mid‐infrared. Time‐bin encoded QKD is simulated, and it is demonstrated that a free‐space QKD link operating in the mid‐infrared outperforms configurations based on conventional near‐infrared wavelengths under various weather scenarios, with a particular ...

High-dimensional coherent one-way quantum key distribution

npj Quantum Information
High-dimensional quantum key distribution (QKD) offers secure communication with key rates that surpass those of QKD protocols utilizing two-dimensional encoding. However, existing high-dimensional QKD protocols require additional experimental resources,

Authenticated QKD Protocol Based on Single-Photon Interference

IEEE Access, 2020
As is known, quantum key distribution (QKD) can provide information-theoretic security under some preconditions, one of which is that the identity of each participant has been authenticated.

QKD in Isabelle -- Bayesian Calculation

CoRR, 2019
In this paper, we present a first step towards a formalisation of the Quantum Key Distribution algorithm in Isabelle. We focus on the formalisation of the main probabilistic argument why Bob cannot be certain about the key bit sent by Alice before he does not have the chance to compare the chosen polarization scheme.

Entanglement model for mode-pairing quantum key distribution

Physical Review Research
Mode-pairing (MP) quantum key distribution (QKD) eliminates the requirements of phase locking and phase tracking compared with twin field (TF) QKD while still surpassing the fundamental rate-distance limit of QKD.

量子密钥分配网络分析

Guangtongxin yanjiu, 2009
量子密钥分配（QKD）网络是由网络节点按照一定的拓扑结构连接而成的。目前出现的QKD网络可根据其节点功能性分为3类:光学节点QKD网络、信任节点QKD网络以及量子节点QKD网络。文章论述了QKD网络的研究进展,对现有的3种网络的结构、性能进行了全面的对比分析。通过对比,提出了一种高效实用的新型QKD网络方案。
