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).

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.

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 ...

High-rate intercity quantum key distribution with a semiconductor single-photon source. [PDF]
Light Sci Appl, 2023 Quantum key distribution (QKD) enables the transmission of information that is secure against general attacks by eavesdroppers. The use of on-demand quantum light sources in QKD protocols is expected to help improve security and maximum tolerable loss ...

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‐

Decoherence-assisted quantum key distribution [PDF]
Scientific ReportsWe 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.

Quantum Key Distribution [PDF]
, 2011 This chapter describes the application of lasers, specifically diode lasers, in the area of quantum key distribution (QKD). First, we motivate the distribution of cryptographic keys based on quantum physical properties of light, give a brief introduction to QKD assuming the reader has no or very little knowledge about cryptography, and briefly present ...

A Proof of the Security of Quantum Key Distribution [PDF]
Journal of Cryptology, 1999 We prove the security of quantum key distribution against the most general attacks which can be performed on the channel, by an eavesdropper who has unlimited computation abilities, and the full power allowed by the rules of classical and quantum physics.
