Quantum key distribution via quantum encryption

, 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.

Practical challenges in quantum key distribution [PDF]

, 2016
Quantum key distribution (QKD) promises unconditional security in data communication and is currently being deployed in commercial applications. Nonetheless, before QKD can be widely adopted, it faces a number of important challenges such as secret key ...

Free-Space Quantum Key Distribution

, 2016
Based on the firm laws of physics rather than unproven foundations of mathematical complexity, quantum cryptography provides a radically different solution for encryption and promises unconditional security.

Satellite-based links for quantum key distribution: beam effects and weather dependence

New Journal of Physics, 2019
The establishment of a world-wide quantum communication network relies on the synergistic integration of satellite-based links and fiber-based networks. The first are helpful for long-distance communication, as the photon losses introduced by the optical

Reliable numerical key rates for quantum key distribution [PDF]

Quantum, 2018
In this work, we present a reliable, efficient, and tight numerical method for calculating key rates for finite-dimensional quantum key distribution (QKD) protocols. We illustrate our approach by finding higher key rates than those previously reported in

Quantum Kolmogorov Complexity and Quantum Key Distribution

, 2009
We discuss the Bennett-Brassard 1984 (BB84) quantum key distribution protocol in the light of quantum algorithmic information. While Shannon's information theory needs a probability to define a notion of information, algorithmic information theory does ...

Experimental Integration of Quantum Key Distribution and Post‐Quantum Cryptography in a Hybrid Quantum‐Safe Cryptosystem

Advanced Quantum Technologies
Quantum key distribution (QKD) and post‐quantum cryptography (PQC) are the two counter measures against cryptographic attacks via quantum computing. While QKD offers information theoretic security but limited authentication scalability, PQC facilitates ...

Quantum Key Distribution

, 2023
AbstractA new class of computers, so-called quantum computers, will soon be able to crack common encryption algorithms. Quantum key distribution is a promising solution to stay secure in the age of the quantum computer, which is progressively getting industrialized in recent years.
