有限经典Bob的量子密钥分发

Quantum key distribution with limited classical Bob

Zhiwei Sun, Ruigang Du, Dongyang Long

摘要:

两个量子密钥分配协议与有限的经典鲍勃谁只执行有限的经典操作(准备一个(新鲜的)量子比特在经典的基础上,并发送它或什么都不做),并证明是完全鲁棒的。由于有限的经典Bob可以确定性地选择比特,我们利用这一特性构造了一个量子安全的直接通信协议,该协议是秘密消息的直接通信,而不需要首先产生共享密钥。

英文摘要:

Two QKD protocols with limited classical Bob who performs only limited classical operations (preparing a (fresh) qubit in the classical basis and send it or doing nothing) are presented and are proved completely robust. As limited classical Bob can deterministically choose the bits, we use the feature to construct a quantum secure direct communication protocol, which is the direct communication of secret messages without first producing a shared secret key.
