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 Using Quantum Faraday Rotators [PDF]
Journal of Physics: Condensed Matter, 2007 We propose a new quantum key distribution (QKD) protocol based on the fully quantum mechanical states of the Faraday rotators. The protocol is unconditionally secure against collective attacks for multi-photon source up to two photons on a noisy ...

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

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.

Loophole-free plug-and-play quantum key distribution
New Journal of Physics, 2021 Robust, simple, and flexible quantum key distribution (QKD) is vital for realizing practical applications of this technique. Contrary to typical phase-coded QKD schemes, the plug-and-play QKD design requires only one arm-length-insensitive interferometer

Quantum key distribution without sending a quantum signal [PDF]
New Journal of Physics, 2015 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

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
