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).

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 ...

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.

Security of quantum key distribution from generalised entropy accumulation. [PDF]
Nat Commun, 2023 The goal of quantum key distribution (QKD) is to establish a secure key between two parties connected by an insecure quantum channel. To use a QKD protocol in practice, one has to prove that a finite size key is secure against general attacks: no matter ...

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

DECOY STATE QUANTUM KEY DISTRIBUTION
International Islamic University Malaysia Engineering Journal, 2010 Experimental weak + vacuum protocol has been demonstrated using commercial QKD system based on a standard bi-directional ‘Plug & Play’ set-up. By making simple modifications to a commercial quantum key distribution system, decoy state QKD allows us to ...

Receiver-Device-Independent Quantum Key Distribution [PDF]
Quantum, 2022 We present protocols for quantum key distribution in a prepare-and-measure setup with an asymmetric level of trust. While the device of the sender (Alice) is partially characterized, the receiver's (Bob's) device is treated as a black-box.

Experimental Twin-Field Quantum Key Distribution over 1000 km Fiber Distance. [PDF]
Physical Review Letters, 2023 Quantum key distribution (QKD) aims to generate secure private keys shared by two remote parties. With its security being protected by principles of quantum mechanics, some technology challenges remain towards practical application of QKD.

Continuous-variable quantum key distribution system: Past, present, and future [PDF]
Applied Physics Reviews, 2023 Quantum key distribution provides secure keys with information-theoretic security ensured by the principle of quantum mechanics. The continuous-variable version of quantum key distribution using coherent states offers the advantages of its compatibility ...
