Quantum Optics with Rydberg Excitons

本计画将研究低温（4K以下）极限下半导体氧化亚铜中电子与空穴的束缚态与微波电磁场的耦合。目的是研究激子态与超导微波谐振器产生的强微波场共振耦合的基本物理，并探索这样的系统是否可以达到量子状态。该学生将与卡迪夫大学的研究人员合作，作为现有合作的一部分。所使用的主要技术将是传统的激光技术，加上晶体生长和表征的常用方法。该项目是一项蓝天研究，现阶段没有与最终用户（行业，政府）的合作计划。所有先前存在的知识产权都是在公共领域开放获取的，预计该项目也将如此。与国防无关，也不会使用核材料或其他受限制的材料。

This project will investigate the coupling between bound states of electrons and holes in the semiconductor cuprous oxide and microwave electromagnetic fields in the low temperature (4K and below) limit. The aim is to study the basic physics of excitonic states resonantly coupled to a strong microwave field produced by a superconducting microwave resonator, and to explore whether such a system can reach the quantum regime. The student will collaborate with researchers at Cardiff University as part of an existing collaboration. The main technique used will be conventional laser technology, plus common methods for crystal growth and characterisation. The project is blue-skies research, with no collaborations with end users (industry, government) planned at this stage. All pre-existing IP is open access in the public domain, and it is anticipated that this will be true for the project. There are no links to defence, and no nuclear or other restricted materials will be used.
