ハイブリッドシステムにおける量子光学の新体制に関する研究

2016财年，我与他人合著了6篇科学论文。还有几篇文章正在撰写中，其中包括一篇关于超导电路的量子光学的大型综述。我在国际会议、研讨会和研讨会上做过11次演讲和1次海报展示。在这6篇文章中，有3篇是原子与光子超强耦合的理论研究。在与其他几位研究人员的合作中，我们已经证明了在这种机制下可能会有大量的新过程，例如，有效的非线性光学模拟和原子之间的多体相互作用。所有这些新过程对于电路量子电动力学(QED)的实验来说都是触手可及的。在一篇文章中，我研究了单个原子与距离很远的多个点上的光子耦合的物理。这种新的量子光学体系可以用声表面波(SAW)来实现。在另一篇文章中，我为牛津大学的一个实验小组提供了理论支持，他们在世界上首次展示了这种锯片的谐振器与超导人造原子之间的耦合。我合著的上一篇文章使用莱格特-加尔格不等式研究了具有多个原子的量子力学的基本检验。

In FY2016, I have been a co-author of 6 submitted scientific articles. Several more articles are in the works, including a large review on quantum optics with superconducting circuits. I have given 11 talks and 1 poster presentation at international conferences, workshops, and seminars. See attached list for details.Among the 6 articles, 3 are theoretical studies of ultrastrong coupling between atoms and photons. In collaboration with several other researchers, we have shown that a wealth of new processes become possible in this regime, e.g., efficient analogues of nonlinear optics and many-body interactions among atoms. All these new processes are within reach for experiments in circuit quantum electrodynamics (QED).In one article, I studied the physics of a single atom coupled to photons at multiple points separated by a large distance. This new regime of quantum optics can be implemented with surface acoustic waves (SAWs). In another article, I provided theoretical support for an experimental group at Oxford who demonstrated, for the first time in the world, coupling between a resonator for such SAWs and a superconducting artificial atom. The last article I co-authored studied fundamental test of quantum mechanics with many atoms using Leggett-Garg inequalities.
