Decoherence-assisted quantum key distribution [PDF]

Scientific Reports
We put forward and demonstrate a controllable decoherence-assisted quantum key distribution scheme. The protocol is based on the possibility of introducing controllable decoherence to polarization qubits using the spatial degree of freedom of light.

Security of Quantum Key Distribution

IEEE Access, 2016
The security issues facing quantum key distribution (QKD) are explained, herein focusing on those issues that are cryptographic and information theoretic in nature and not those based on physics. The problem of security criteria is addressed.

Mode-pairing quantum key distribution [PDF]

Nature Communications, 2022
Measurement-device-independent QKD schemes suffer from a trade-off between ease of implementation (avoiding the need for global phase locking) and high rates (quadratic improvement in rate).

Quantum key distribution without sending a quantum signal [PDF]

New Journal of Physics, 2015
Quantum Key Distribution is a quantum communication technique in which random numbers are encoded on quantum systems, usually photons, and sent from one party, Alice, to another, Bob. Using the data sent via the quantum signals, supplemented by classical

DECOY STATE QUANTUM KEY DISTRIBUTION

International Islamic University Malaysia Engineering Journal, 2010
Experimental weak + vacuum protocol has been demonstrated using commercial QKD system based on a standard bi-directional ‘Plug & Play’ set-up. By making simple modifications to a commercial quantum key distribution system, decoy state QKD allows us to ...

Receiver-Device-Independent Quantum Key Distribution [PDF]

Quantum, 2022
We present protocols for quantum key distribution in a prepare-and-measure setup with an asymmetric level of trust. While the device of the sender (Alice) is partially characterized, the receiver's (Bob's) device is treated as a black-box.

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 ...

Cost-Optimization-Based Quantum Key Distribution over Quantum Key Pool Optical Networks

Entropy, 2023
The Measurement-Device-Independent-Quantum Key Distribution (MDI-QKD) has the advantage of extending the secure transmission distances. The MDI-QKD combined with the Hybrid-Trusted and Untrusted Relay (HTUR) is used to deploy large-scale QKD networks ...
