| 摘 要： | 提出一个基于单光子偏振的量子密钥分配方案.在这个方案里, Alice首先制备一串任意单光子态,然后发送给Bob.Bob只需对其进行一个U操作,再发回Alice.最后Alice对单光子态进行测量,即可实现量子密钥分配.此方案需要一个无噪声信道,优点在于仅仅需要单光子态,以及局域操作和单光子偏振态的测量,这些都非常易于实现.最后其安全性也是有理论保证的.

| Abstract: | A quantum key distribution scheme based on single-photon polarization encoding was presented.In the protocol,Alice first sends string photons to Bob at random states of four single- photon states.Bob then does a unitary operation on it,sends it back to Alice and then a single photon is measured by Alice at last.The quantum key distribution is accomplished.The protocol needs a noiseless subspaces or subsystems.And the advantage is that it only needs single-photon states,local operations and polarization meas... |
