摘要:

超强耦合可以允许量子技术发展的更快操作,但代价是对新类型的固有误差的敏感性增加。我们研究了超导电路QED体系在超强耦合下的态转移。使用最优控制方法,我们找到了一个协议弹性的主要来源的错误,来自腔损耗的动态Casimir效应的相互作用。

英文摘要:

Ultrastrong coupling may allow faster operations for the development of quantum technologies at the expenses of increased sensitivity to new kind of intrinsic errors. We study state transfer in superconducting circuit QED architectures in the ultrastrong coupling regime. Using optimal control methods we find a protocol resilient to the main source of errors, coming from the interplay of the dynamical Casimir effect with cavity losses.
