摘要
In this Letter, we propose a quantum secure direct communication protocol based on single photons without quantum memories. In the proposed protocol, quantum states are transmitted in a stream but not in a quantum data block, hence, quantum memories are unnecessary. Compare with other protocols the advantages of our protocol are smaller quantum space usage, lower cost and more easily being implemented experimentally.
