纳米力学模式间的量子隐形传态

Quantum teleportation between nanomechanical modes

L. Tian, S. M. Carr

摘要:

研究了两个纳米力学模之间无局域相互作用的量子隐形传态方案。纳米机械模式线性耦合到由传输线和约瑟夫森结组成的超导电路的连续可变模式并通过连续可变模式连接。计算了有限温度下高斯态的保真度和非单位探测器效率。对于相干态,在很大的参数范围内,可以获得超过经典极限1/2的保真度。

英文摘要:

We study a quantum teleportation scheme between two nanomechanical modes without local interaction. The nanomechanical modes are linearly coupled to and connected by the continuous variable modes of a superconducting circuit consisting of a transmission line and Josephson junctions. We calculate the fidelity of transferring Gaussian states at finite temperature and non-unit detector efficiency. For coherent state, a fidelity above the classical limit of 1/2 can be achieved for a large range of parameters.
