Quantum key distribution with quantum walks [PDF]
Quantum Information Processing 17:288, 2018, 2017 Quantum key distribution is one of the most fundamental cryptographic protocols. Quantum walks are important primitives for computing. In this paper we take advantage of the properties of quantum walks to design new secure quantum key distribution schemes. In particular, we introduce a secure quantum key-distribution protocol equipped with verification

Implementation Security in Quantum Key Distribution [PDF]
Advanced Quantum Technologies, 2023 AbstractThe 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‐variable QKD setups.

No Signalling and Quantum Key Distribution [PDF]
Physical Review Letters, 2005 Standard quantum key distribution protocols are provably secure against eavesdropping attacks, if quantum theory is correct. It is theoretically interesting to know if we need to assume the validity of quantum theory to prove the security of quantum key ...

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.

Fully Passive Quantum Key Distribution [PDF]
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.

Twin-field quantum key distribution without optical frequency dissemination. [PDF]
Nat Commun, 2023 Twin-field (TF) quantum key distribution (QKD) has rapidly risen as the most viable solution to long-distance secure fibre communication thanks to its fundamentally repeater-like rate-loss scaling.

Quantum key distribution without alternative measurements [PDF]
, 2000 Entanglement swapping between Einstein-Podolsky-Rosen (EPR) pairs can be used to generate the same sequence of random bits in two remote places. A quantum key distribution protocol based on this idea is described.

Quantum Kolmogorov Complexity and Quantum Key Distribution [PDF]
Physical Review A, 2009 We discuss the Bennett-Brassard 1984 (BB84) quantum key distribution protocol in the light of quantum algorithmic information. While Shannon's information theory needs a probability to define a notion of information, algorithmic information theory does ...
