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.

在2016财年，我是6个提交科学文章的合着者。还有更多文章正在进行中，包括对具有超导电路的量子光学元件进行的大量审查。我在国际会议，研讨会和研讨会上进行了11次演讲和1个海报演讲。有关详细信息，请参见附件列表。在6篇文章中，有3篇是原子和光子之间超术耦合的理论研究。与其他几位研究人员合作，我们表明，在这种制度中，有大量的新过程，例如，非线性光学的有效类似物和原子之间的多体相互作用。对于电路量子电动力学的实验（QED），所有这些新过程都可以实现。在一条文章中，我研究了一个单个原子的物理学，该原子在多个点以大距离分离的多个点耦合到光子。这种新的量子光学机构可以通过表面声波（锯）实现。在另一篇文章中，我为牛津大学的一个实验组提供了理论支持，该组织在世界上首次证明了这种锯子的谐振器与超导性人工原子之间的耦合。我共同撰写的最后一篇文章研究了使用Leggett-Garg不平等的许多原子研究量子力学的基本测试。
