Superconducting detectors for observing photons, phonons and spins in diamond

光学机械设备使用光来测量具有量子限制灵敏度的机械对象的位置的波动。这些设备可以在从大规模（例如，从LIGO到微观（例如激光捕获原子的振动），是机械物体的基础研究以及用于检测力和存储信息的实用仪器的基础。研究工具和仪器的要求中描述的设备迫切需要使用巴克莱实验室创建的光学机械设备进行世界领先的实验，以探测和控制机械谐振器的量子特性，并产生量子光源，这些光源是未来量子信息处理技术的基本要素。申请的设备资金补充了2016年和2017年授予Barclay实验室的NSERC Discovery，Accelerator，CREATE和战略合作伙伴关系资金，以支持HQP在量子自旋光力学领域的工作，并且是HQP成功完成项目所急需的。

Optomechanical devices use light to measure fluctuations in the position of mechanical objects with quantum limited sensitivity. These devices can be implemented over size scales ranging from massive (e.g., LIGO) to microscopic (e.g. vibrations of laser trapped atoms), and underlie fundamental studies of mechanical objects as well as practical instruments for detecting forces and storing information. The equipment described in this request for Research Tools and Instruments is urgently needed to perform world leading experiments using optomechanical devices created in the Barclay lab to probe and control the quantum properties of mechanical resonators and to generate sources of quantum light that are essential elements for future quantum information processing technologies. The requested funding for equipment complements NSERC Discovery, Accelerator, CREATE and Strategic Partnership funding awarded to the Barclay lab in 2016 and 2017 to support HQP working in the area of quantum spin-optomechanics, and is critically needed for HQP to successfully complete their projects.
