Based on Bell 202 communication standards, HART protocols transfer data with different frequency signals and plus with 4~ 20mA of analog signals. 该协议基于Bell202通信标准,在4~20mA的模拟信号上叠加不同的频率信号来传送数字信号。
By making use of the standard transport protocols and the Bell measurement bases, we investigate quantum teleportation with quantum dot as quantum channel. Our results show that the fidelity of teleportation is highly stable and quality. 利用标准传输协议和Bell基测量的方法,我们研究了当量子点作为量子信道时,量子隐形传输的传输质量问题,我们获得了高稳定和高保真的传输态。
