摘要:

提出了基于纯纠缠态和基于$d$维单光子态的两种确定性安全量子通信方案。在这两种方案中,两个授权用户只需要进行单光子测量,这使得这两种方案在实际应用中比其他方案更加方便。虽然每个量子比特可以在传输额外的经典比特后读出,但用户不必传输发送者和接收者之间距离的两倍的量子比特,这将提高他们的比特率和安全性。各方使用诱饵光子有效地检查窃听。第一种方案的明显优点是纯纠缠源在现有技术条件下是可行的。

英文摘要:

Two deterministic secure quantum communication schemes are proposed, one based on pure entangled states and the other on $d$-dimensional single-photon states. In these two schemes, only single-photon measurements are required for the two authorized users, which makes the schemes more convenient than others in practical applications. Although each qubit can be read out after a transmission of additional classical bit, it is unnecessary for the users to transmit qubits double the distance between the sender and the receiver, which will increase their bit rate and their security. The parties use decoy photons to check eavesdropping efficiently. The obvious advantage in the first scheme is that the pure entangled source is feasible with present techniques.
