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.

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).

A Proof of the Security of Quantum Key Distribution [PDF]

Journal of Cryptology, 1999
We prove the security of quantum key distribution against the most general attacks which can be performed on the channel, by an eavesdropper who has unlimited computation abilities, and the full power allowed by the rules of classical and quantum physics.

Phase-Matching Quantum Key Distribution [PDF]

Physical Review X, 2018
Quantum key distribution allows remote parties to generate information-theoretic secure keys. The bottleneck throttling its real-life applications lies in the limited communication distance and key generation speed, due to the fact that the information ...

Quantum key distribution with chromatic codes [PDF]

Light: Science & Applications
Quantum key distribution with different frequency codes is demonstrated with a reconfigurable entanglement distribution network, which is essential for scalable and resource-efficient quantum communications.

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.
