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 cryptography: Public key distribution and coin tossing [PDF]
Theoretical Computer Science, 2014 When elementary quantum systems, such as polarized photons, are used to transmit digital information, the uncertainty principle gives rise to novel cryptographic phenomena unachievable with traditional transmission media, e.g. a communications channel on

Security of device-independent quantum key distribution protocols: a review [PDF]
Quantum, 2022 Device-independent quantum key distribution (DI-QKD) is often seen as the ultimate key exchange protocol in terms of security, as it can be performed securely with uncharacterised black-box devices.

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 ...

Implementation Security in Quantum Key Distribution [PDF]
Advanced Quantum Technologies, 2023 The problem of implementation security in quantum key distribution (QKD) refers to the difficulty of meeting the requirements of mathematical security proofs in real‐life QKD systems. Here, a succint review is provided on this topic, focusing on discrete‐

Simple proof of security of the BB84 quantum key distribution protocol [PDF]
Physical Review Letters, 2000 We prove that the 1984 protocol of Bennett and Brassard (BB84) for quantum key distribution is secure. We first give a key distribution protocol based on entanglement purification, which can be proven secure using methods from Lo and Chau's proof of ...

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 ...
