Quantum Key Distribution Using Quantum Faraday Rotators [PDF]
Journal of Physics: Condensed Matter, 2007 We propose a new quantum key distribution (QKD) protocol based on the fully quantum mechanical states of the Faraday rotators. The protocol is unconditionally secure against collective attacks for multi-photon source up to two photons on a noisy ...

Quantum Kolmogorov Complexity and Quantum Key Distribution [PDF]
Physical Review A, 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 ...

Quantum repeaters and quantum key distribution: analysis of secret key rates [PDF]
Physical Review A, 2013 We analyze various prominent quantum repeater protocols in the context of long-distance quantum key distribution. These protocols are the original quantum repeater proposal by Briegel, D\"ur, Cirac and Zoller, the so-called hybrid quantum repeater using ...
