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).

Practical challenges in quantum key distribution [PDF]
npj Quantum Information, 2016 Quantum key distribution (QKD) promises unconditional security in data communication and is currently being deployed in commercial applications. Nonetheless, before QKD can be widely adopted, it faces a number of important challenges such as secret key ...

Decoy State Quantum Key Distribution [PDF]
Physical Review Letters, 2005 There has been much interest in quantum key distribution. Experimentally, quantum key distribution over 150 km of commercial Telecom fibers has been successfully performed. The crucial issue in quantum key distribution is its security. Unfortunately, all

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 ...

Layered Quantum Key Distribution [PDF]
Physical Review A, 2017 We introduce a family of QKD protocols for distributing shared random keys within a network of $n$ users. The advantage of these protocols is that any possible key structure needed within the network, including broadcast keys shared among subsets of ...

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
