Entanglement-enhanced quantum key distribution

Physical Review A, 2008
We present and analyze a quantum key distribution protocol based on sending entangled N-qubit states instead of single-qubit ones as in the trail-blazing scheme by Bennett and Brassard (BB84). Since the qubits are sent individually, an eavesdropper is limited to accessing them one by one.

On the problem of non-zero word error rates for fixed-rate error correction codes in continuous variable quantum key distribution

New Journal of Physics, 2017
The maximum operational range of continuous variable quantum key distribution protocols has shown to be improved by employing high-efficiency forward error correction codes.

Frequency-bin entanglement-based Quantum Key Distribution

npj Quantum Information
Entanglement is an essential ingredient in many quantum communication protocols. In particular, entanglement can be exploited in quantum key distribution (QKD) to generate two correlated random bit strings whose randomness is guaranteed by the nonlocal ...

Towards global quantum key distribution

Nature Reviews Electrical Engineering
Quantum Key Distribution (QKD) supports the negotiation and sharing of private keys with unconditional security between authorized parties. Over the years, theoretical advances and experimental demonstrations have successfully transitioned QKD from laboratory research to commercial applications.

High-Dimensional Quantum Key Distribution in Quantum Access Networks

IEEE Photonics Journal
We investigate the use of high-dimensional quantum key distribution (HD-QKD) for wireless access to hybrid quantum-classical networks. We use $d$-dimensional time-phase encoded states to exchange a secret key between an indoor wireless user and the ...

Quantum vs post‐quantum security for future networks: Survey

Cyber Security and Applications
Classical cryptography (crypt) schemes (sche) have been compromised by the practical results on quantum (q) computers in recent years. Nowadays these sche ‘s can be compromised by using the Shor's methodology. This paper provides a detailed survey of the
