Mode-pairing quantum key distribution. [PDF]

Nat Commun, 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).

High-rate intercity quantum key distribution with a semiconductor single-photon source. [PDF]

Light Sci Appl, 2023
Quantum key distribution (QKD) enables the transmission of information that is secure against general attacks by eavesdroppers. The use of on-demand quantum light sources in QKD protocols is expected to help improve security and maximum tolerable loss ...

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 ...

Decoherence-assisted quantum key distribution. [PDF]

Sci Rep
We 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.

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 Key Distribution without sending a Quantum Signal [PDF]

New Journal of Physics, 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

Symmetric Autocompensating Quantum Key Distribution [PDF]

, 2003
We present quantum key distribution schemes which are autocompensating (require no alignment) and symmetric (Alice and Bob receive photons from a central source) for both polarization and time-bin qubits.

Decoy State Quantum Key Distribution [PDF]

, 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
