Finite-key analysis of a practical decoy-state high-dimensional quantum key distribution

, 2016
Compared with two-level quantum key distribution (QKD), highdimensional QKD enable two distant parties to share a secret key at a higher rate. We provide a finite-key security analysis for the recently proposed practical highdimensional decoy-state QKD ...

Tunable Coupler–Augmented Microrings: Reconfigurable Q‐Factor Control for Foundry‐Scale Quantum Light Sources

Nanophotonics, Volume 15, Issue 6, 27 March 2026.
Scalable quantum photonics require robust realization of quantum light sources for foundry‐scale fabrication. An interferometrically coupled silicon nitride microring resonator enables post‐fabrication control of bus–ring coupling. Thermal phase shifters adjust the Q‐factor and the pair generation rate, revealing that optimal generation does not occur ...

Simple and Rigorous Proof Method for the Security of Practical Quantum Key Distribution in the Single-Qubit Regime Using Mismatched Basis Measurements

Quantum Reports, 2023
Quantum key distribution (QKD) protocols aim at allowing two parties to generate a secret shared key. While many QKD protocols have been proven unconditionally secure in theory, practical security analyses of experimental QKD implementations typically do

Detector-device-independent QKD: security analysis and fast implementation

, 2016
One of the most pressing issues in quantum key distribution (QKD) is the problem of detector side- channel attacks. To overcome this problem, researchers proposed an elegant "time-reversal" QKD protocol called measurement-device-independent QKD (MDI-QKD),

Practical long-distance quantum key distribution system using decoy levels [PDF]

, 2008
Quantum key distribution (QKD) has the potential for widespread real-world applications. To date no secure long-distance experiment has demonstrated the truly practical operation needed to move QKD from the laboratory to the real world due largely to ...

A Survey of Machine Learning Assisted Continuous-Variable Quantum Key Distribution

Information, 2023
Continuous-variable quantum key distribution (CV-QKD) shows potential for the rapid development of an information-theoretic secure global communication network; however, the complexities of CV-QKD implementation remain a restrictive factor.

Continuous-variable measurement-device-independent quantum key distribution with photon subtraction

, 2018
It has been found that non-Gaussian operations can be applied to increase and distill entanglement between Gaussian entangled states. We show the successful use of the non-Gaussian operation, in particular, photon subtraction operation, on the continuous-

Asymmetric Protocols for Scalable High-Rate Measurement-Device-Independent Quantum Key Distribution Networks [PDF]

, 2019
Measurement-device-independent quantum key distribution (MDI-QKD) can eliminate detector side channels and prevent all attacks on detectors. The future of MDI-QKD is a quantum network that provides service to many users over untrusted relay nodes.
