摘要
为了将量子的安全性引入云计算网络中,提出一种将两种信息格式互相转换的方法,其中C-Q变换是将经典信息的0-1码经过量子门操作变为|0〉,|1〉态,而Q-C变换是利用光敏二极管和偏振片,将量子态|φ〉变为经典信息的0-1码。对于整个的转换网,进行转换效率和吞吐率的仿真,结果表明,该模型的转换效率可以达到90%,吞吐率也可达到30 Mb/s。
In order to introduce the quantum security into cloud computing network, a method called Classical Quantum Switching is proposed to switch the two information format. The C-Q switching let classical 0, 1 become ｜]0〉, ｜ 1〉 after the quantum gate operations; The Q-C switching let state ｜0〉, ｜ 1〉 become classical O, 1 after a polarizer and a photodiode. A simulation of conversion effciency and throughput within the whole network efficiency of this model can reach 90%, the throughput can achieve shows that the conversion 30 Mb/s.
