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).

Symmetric Autocompensating Quantum Key Distribution [PDF]
SPIE Proceedings, 2003 We present quantum key distribution schemes which are autocompensating (require no alignment) and symmetric (Alice and Bob receive photons from a central source) for both polarization and time-bin qubits.

Quantum Key Distribution [PDF]
ACM Computing Surveys, 2020 The convergence of quantum cryptography with applications used in everyday life is a topic drawing attention from the industrial and academic worlds. The development of quantum electronics has led to the practical achievement of quantum devices that are already available on the market and waiting for their first application on a broader scale.

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 ...

Fully Passive Quantum Key Distribution
Physical Review Letters, 2023 Passive implementations of quantum key distribution (QKD) sources are highly desirable as they eliminate side-channels that active modulators might introduce. Up till now, passive decoy-state and passive encoding BB84 schemes have both been proposed.

Quantum dense key distribution [PDF]
Physical Review A, 2004 This paper proposes a new protocol for quantum dense key distribution. This protocol embeds the benefits of a quantum dense coding and a quantum key distribution and is able to generate shared secret keys four times more efficiently than BB84 one. We hereinafter prove the security of this scheme against individual eavesdropping attacks, and we present ...

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 ...
