| Quantum Key Distribution Using Quantum Faraday Rotators (2006) | |||||||||
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.. Comment: 7 pages, 7 EPS figures | |||||||||
