Quantum Key Distribution Using Quantum Faraday Rotators
arXiv:quant-ph/0612208 · doi:10.1088/0953-8984/20/27/275242
Abstract
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 environment. It is also robust against impersonation attacks. The protocol may be implemented experimentally with the current spintronics technology on semiconductors.
