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.

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 ...

Mode-pairing quantum key distribution

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).

40-user fully connected entanglement-based quantum key distribution network without trusted node

PhotoniX, 2022
Quantum key distribution (QKD) would play an important role in future information technologies due to its theoretically proven security based on the laws of quantum mechanics.

Higher-rate relativistic quantum key distribution

Scientific Reports, 2021
One of the major problems in the field of quantum key distribution (QKD) is the low key rates at which the systems operate. The reasons for this are the processes used to ensure the key distribution itself: sifting, parameter estimation, key ...
