Eavesdropping Detection in BB84 Quantum Key Distribution Protocols

open access: yesIEEE Transactions on Network and Service Management, 2022
The nature of quantum mechanics provides us with an opportunity to statistically detect eavesdropping in quantum key distribution (QKD) protocols, which is unimaginable in classical digital communications.

Long-lived and multiplexed atom-photon entanglement interface with feed-forward-controlled readouts

open access: yesCommunications Physics, 2021
The quantum interface to generate entanglement between a flying photonic qubit and a stationary qubit is a key functionality for the quantum internet. The authors demonstrate a multiplexed quantum interface that stores three long-lived spin-wave qubits ...

SECURITY OF QUANTUM KEY DISTRIBUTION [PDF]

open access: yesInternational Journal of Quantum Information, 2008
Quantum Information Theory is an area of physics which studies both fundamental and applied issues in quantum mechanics from an information-theoretical viewpoint. The underlying techniques are, however, often restricted to the analysis of systems which satisfy a certain independence condition.

The Case for Quantum Key Distribution [PDF]

open access: yes, 2009
Quantum key distribution (QKD) promises secure key agreement by using quantum mechanical systems. We argue that QKD will be an important part of future cryptographic infrastructures.

Improving Parameter Optimization in Decoy-State Quantum Key Distribution

open access: yesQuantum Engineering, 2022
Quantum key distribution (QKD) enables two remote users to share a string of key bits with information-theoretical security. Parameter optimization is a crucial step in achieving optimal performance in practical QKD systems. In general, such optimization

Quantum key distribution via quantum encryption

open access: yes, 2001
A quantum key distribution protocol based on quantum encryption is presented in this Brief Report. In this protocol, the previously shared Einstein-Podolsky-Rosen pairs act as the quantum key to encode and decode the classical cryptography key.
