Quantum phononics with 2D materials

本博士将开发一种利用过渡金属-二硫化物（TMD）单层膜耦合光（光子）、物质（自旋）和运动（声子）的装置。这样的装置将为制备和控制声子的任意量子态提供基本的构建块；使不同的量子系统通过声子总线连接-克服实现基于量子计算和实现量子辅助力传感所面临的主要问题。该学生将致力于开发具有高机械质量因子（创造高量子相干声子的重要先决条件）的自由悬浮TMD机械振荡器（MOs）并探索其机械特性。这将开启一个独特而令人兴奋的前景，即声子与光学主动量子发射器（这些本质上是“人造原子”）耦合在tmd内，该小组最近一直在探索。

This PhD will develop a device for coupling light (photons), matter (spins) and motion (phonons) using transition-metal-dichalcogenide (TMD) monolayers. Such a device would provide the basic building block for preparing and controlling arbitrary quantum states of phonons; enabling different quantum systems to be connected via a phonon bus - overcoming a major problem facing the implementation of quantum-based computing and implementing quantum-assisted force sensing. The student will aim to develop freely suspended TMD mechanical oscillators (MOs) with high mechanical quality-factors (a vital pre-requisite for creating phonons with high quantum coherence) and probe their mechanical properties. This would open up the unique and exciting prospect of coupling phonons with optically active quantum emitters (these are essentially "artificial atoms") hosted within TMDs that the group has been recently exploring.
