| 摘 要： | 本文提出了一个基于SQUIDs和腔场的大失谐相互作用传送量子信息的方案，此方案可以直接地、百分之百地实现量子信息的传送。该方案中腔场和SQUIDs系统之间没有量子信息的传递，腔场只是虚激发, 这样对腔的品质因子的要求大大的降低了。同时也可以在SQUIDs之间建立传送量子信息的量子网络。

| Abstract: | We propose a scheme for transferring Quantum information via superconducting quantum interference device (SQUID) qubits and cavity field interaction with a large detuning. In the scheme, no quantum information is transferred between the SQUIDs and the cavities, the cavity-fields are only virtually excited, thus the requirement on the quality factor of the cavities is greatly relaxed. In addition, in the scheme the quantum information can be directly transferred with a successful probability of 100 % in a simple manner. And meanwhile we can establish a network for transferring quantum information between SQUID qubits. |
