Quantum Key Distribution without sending a Quantum Signal [PDF]
, 2014 Quantum Key Distribution is a quantum communication technique in which random numbers are encoded on quantum systems, usually photons, and sent from one party, Alice, to another, Bob. Using the data sent via the quantum signals, supplemented by classical

Analysis of Single Photon Detectors in Differential Phase Shift Quantum Key Distribution [PDF]
arXiv, 2023 In the current research work, an analysis of differential phase shift quantum key distribution using InGaAs/InP and Silicon-APD (avalanche photodiode) as single photon detectors is performed. Various performance parameters of interest such as shifted key rate, secure key rate, and secure communication distance obtained are investigated. In this optical

Long-Distance Continuous-Variable Quantum Key Distribution over 202.81 km of Fiber [PDF]
Phys. Rev. Lett. 125, 010502 (2020), 2020 Quantum key distribution provides secure keys resistant to code-breaking quantum computers. The continuous-variable version of quantum key distribution offers the advantages of higher secret key rates in metropolitan areas, as well as the use of standard telecom components that can operate at room temperature.

Quantum Key Distribution with Qubit Pairs [PDF]
Journal of Quantum Information Science, 4, 129-132 (2014), 2013 We propose a new Quantum Key Distribution method in which Alice sends pairs of qubits to Bob, each in one of four possible states. Bob uses one qubit to generate a secure key and the other to generate an auxiliary key. For each pair he randomly decides which qubit to use for which key.

Quantum key distribution via quantum encryption
, 2001 A quantum key distribution protocol based on quantum encryption is presented in this Brief Report. In this protocol, the previously shared Einstein-Podolsky-Rosen pairs act as the quantum key to encode and decode the classical cryptography key.

Space division multiplexing chip-to-chip quantum key distribution [PDF]
Scientific Reports 7, Article number: 12459 (2017), 2017 Quantum cryptography is set to become a key technology for future secure communications. However, to get maximum benefit in communication networks, transmission links will need to be shared among several quantum keys for several independent users.

Quantum Key Distribution over Probabilistic Quantum Repeaters
, 2010 A feasible route towards implementing long-distance quantum key distribution (QKD) systems relies on probabilistic schemes for entanglement distribution and swapping as proposed in the work of Duan, Lukin, Cirac, and Zoller (DLCZ) [Nature 414, 413 (2001)]

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
