摘要:

在电路量子电动力学系统中考虑超导量子点接触。我们研究了三种不同的配置,可与当前的技术,量子点接触电流耦合到共面波导谐振器。此外,我们证明了强和超强耦合制度可以实现与现实的参数,允许超导量子点接触和量子化腔内场之间的相干交换。

英文摘要:

We consider a superconducting quantum point contact in a circuit quantum electrodynamics setup. We study three different configurations, attainable with current technology, where a quantum point contact is coupled galvanically to a coplanar waveguide resonator. Furthermore, we demonstrate that the strong and ultrastrong coupling regimes can be achieved with realistic parameters, allowing the coherent exchange between a superconducting quantum point contact and a quantized intracavity field.
