Cavity Quantum Optomechanics

腔量子光学利用辐射-压力相互作用和量子光学的工具，将对单个量子系统的控制扩展到宏观区域。该领域目前因其为基础科学和应用科学做出贡献的潜力而受到人们的兴趣激增，目前的研究方向包括量子重力的桌面测试和高精度弱力传感器的开发。在这个博士学位中，Lars Freisem将研究如何产生和观察力学振子的非经典运动状态的技术。然后，这些状态将被用于经验性地研究退相干机制，以及开发新型的弱力传感器。

Cavity quantum optomechanics uses the radiation-pressure interaction and the tools of quantum optics to extend the control of individual quantum systems to a macroscopic regime. The field is currently receiving a surge of interest for its potential to contribute to both fundamental and applied science with current research directions including table-top tests of quantum gravity and the development of high-precision weak-force sensors. In this PhD, Lars Freisem will investigate techniques how to generate and observe non-classical states of motion of mechanics oscillator. These states will then be used to empirically study decoherence mechanisms as well as develop new types of weak force sensors.
