噪声信道下的无差错量子通信

Error free quantum communication through noisy channels

Anders Soerensen, Klaus Moelmer

摘要:

我们提出了一种利用非共振场与原子的色散相互作用在遥远的量子比特之间实现量子逻辑门的方法。我们提出的方案是理想的工作,即使在用于通信的光子通道中存在错误。对误差的稳定性来自于一种矛盾的情况,即传输的光子不携带关于量子比特状态的信息。与以前的建议相比,理想的通信[物理学评论快报。78,4293(1997)]我们的建议只涉及发送和接收设备中的单个原子。

英文摘要:

We suggest a method to perform a quantum logic gate between distant qubits by off-resonant field-atom dispersive interactions. The scheme we present is shown to work ideally even in the presence of errors in the photon channels used for communication. The stability against errors arises from the paradoxical situation that the transmitted photons carry no information about the state of the qubits. In contrast to a previous proposal for ideal communication [Phys. Rev. Lett. 78, 4293 (1997)] our proposal only involves single atoms in the sending and receiving devices.
