基于量子法拉第旋转器的量子密钥分发

Quantum Key Distribution Using Quantum Faraday Rotators

Taeseung Choi, Mahn-Soo Choi

摘要:

基于法拉第旋转器的全量子力学态,提出了一种新的量子密钥分发(QKD)协议。该协议在噪声环境下对最多两个光子的多光子源的集体攻击是无条件安全的。它还可以抵抗模拟攻击。该协议可以用半导体上的当前自旋电子学技术实验性地实现。

英文摘要:

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.
