TLDR
The noisy quantum channel is modeled and implemented by the redundancy-free quantum error correction scheme which provides better security and throughput efficiency as shown in simulation results.Abstract:
Quantum key distribution is an effective encryption technique which can be used to perform secure quantum communication between satellite and ground stations. Quantum cryptography enhances security in various networks such as optical fibers and wireless networks. In addition to this, these networks become vulnerable in presence of high attenuation due to atmospheric effects and noise. Hence, errors occurs due to decoherence. The noisy quantum channel is modeled and implemented by the redundancy-free quantum error correction scheme which provides better security and throughput efficiency as shown in simulation results.read more

Performance On The Discrete Variable Based Satellite-to-Ground Quantum Key Distribution Links
TL;DR: Evaluating the available secure key lengths of the satellite-to-ground quantum key distribution (QKD) systems under multiple scenarios shows that the amount of the secure key reduces slowly as the orbit height grows from 200km to 1100km, and the BBM92 protocol based QKD systems are much sensitive to the orbit Height.

Quantum cryptography
TL;DR: A protocol for coin-tossing by exchange of quantum messages is presented, which is secure against traditional kinds of cheating, even by an opponent with unlimited computing power, but ironically can be subverted by use of a still subtler quantum phenomenon, the Einstein-Podolsky-Rosen paradox.
