Integration of Quantum Key Distribution in the SSL/TLS handshake protocol [PDF]

open access: yes, 2022
Quantum Key Distribution (QKD) is a technology, based on the quantum laws of physics, rather than the assumed computation complexity of mathematical problems, to generate and distribute provably secure cipher keys over unsecured channels.

Security‐Enhanced Differential Binary‐Phase‐Shift‐Keying Quantum Key Distribution With a Wavelength‐Switchable Single‐Photon Carrier

open access: yesAdvanced Photonics Research, Volume 7, Issue 6, June 2026.
A single‐chip dual‐wavelength coherent photon source is proposed to add parametric uncertainty and improve the security of single‐photon differential binary‐phase‐shift‐keying quantum key distribution. This wavelength‐uncertain coding or decoying operation enables flexible and secure D‐BPSK‐QKD transmission over a wavelength‐division‐multiplexed ...

Adaptive Modulation for Continuous-Variable Quantum Key Distribution With Real Local Oscillators Under Phase Attack

open access: yesIEEE Photonics Journal, 2021
Continuous-variable quantum key distribution (CV-QKD) with a real local oscillator (LO) experiences a phase attack security challenge due to the reference pulses transmitted along with quantum signals over an unsecure quantum channel.

Asymmetric Measurement-Device-Independent Quantum Key Distribution through Advantage Distillation

open access: yes, 2023
Measurement-device-independent quantum key distribution (MDI-QKD) completely closes the security loopholes caused by the imperfection of devices at the detection terminal. Commonly, a symmetric MDI-QKD model is widely used in simulations and experiments.

A new quantum key distribution protocol to reduce afterpulse and dark counts effects

open access: yesResults in Optics
The most important goal of quantum communication is to distribute the encryption key between the transmitter and the receiver. The optimal situation in Quantum Key Distribution (QKD) between transmitter and receiver is to increase the key distribution ...

Dynamic Search‐Based Cluster Head Selection Method for Resource Occupation Protection Switching in Optical Fiber Communication Networks

open access: yesEngineering Reports, Volume 8, Issue 6, June 2026.
This paper proposes a dynamic search cluster head selection method for resource occupancy protection switching. By integrating multidimensional fitness functions, energy consumption models, and closed‐loop control mechanisms, and combining optimized dynamic search strategies, the optimal cluster head is selected.

Preserving Quantum Coherence in Thermal Noisy Systems Via Qubit Frequency Modulation

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 6, June 2026.
Frequency modulation is shown to preserve quantum coherence in a thermal phase‐covariant environment only under specific noise conditions. It protects a qubit against thermal dissipation from a Lorentzian reservoir, but fails against thermal pure dephasing from an Ohmic reservoir.
