一种新颖的基于类GHZ态的两方半量子密钥分配协议

In this paper, we propose a novel two-party semiquantum key distribution (SQKD) protocol by only employing one kind of GHZ-like state. The proposed SQKD can create private shared between quantum party with unlimited abilities and classical limited without the existence third party. doesn't need Hadamard gate or entanglement swapping. Detailed security analysis turns out that resist various famous attacks from an outside eavesdropper, such as Trojan horse attacks, entangle-measure attack, double CNOT measure-resend attack intercept-resend attack.
