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.

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 ...

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 [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

Quantum Key Distribution with Classical Bob [PDF]
Physical Review Letters, 2007 Secure key distribution among two remote parties is impossible when both are classical, unless some unproven (and arguably unrealistic) computation-complexity assumptions are made, such as the difficulty of factorizing large numbers. On the other hand, a

Chip-based quantum key distribution [PDF]
Nature Communications, 2017 Quantum key distribution has not been widely adopted in part due to technical hurdles preventing it being fully integrated in classical communication networks.

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.

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 ...
