摘要：

The security of quantum communications lies in the capability of the legitimate parties to detect eavesdropping. Here we propose to use delayed measurement to increase the efficiency of protocols of quantum key distribution and quantum secret sharing that uses a random choice of measuring-basis. In addition to a higher efficiency, these measures also bring the benefit of much reduced amount of classical coin communications.
