Electronic and magnetic spectroscopy system for spin-optomechanics

光学机械设备使用光作为标尺来测量机械物体位置的微小波动。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。本研究工具和仪器申请中所述的设备迫切需要使用光学机械设备进行世界领先的实验，以控制和测量材料的纳米级电子和磁性-自旋-这是未来量子信息处理和传感技术的基本要素。申请的设备资金补充了2016年授予巴克莱实验室的NSERC发现，加速器和战略合作伙伴关系资金，以支持HQP研究自旋光学力学，并且这些HQP成功完成其项目至关重要。 在过去的两年中，巴克莱实验室的HQP开发了纳米级光学机械设备，在两个方面取得了突破：他们展示了纳米级空腔光学机械传感器的首批应用之一，并创造了世界上第一个单晶金刚石光学机械设备。除了显示出创纪录的低机械损耗和对外力的高灵敏度等特性外，这些器件还率先将腔光学力学与电子和磁自旋联系起来。如果它们可以在低温和精确控制的磁场和RF场中操作，并且如果它们的自旋可以精确寻址，它们将为光机械探测和控制自旋系统提供无与伦比的平台，并将对量子信息处理应用产生浓厚的兴趣。然而，实现这些要求所需的设备目前在巴克莱实验室中不可用。 对研究工具和仪器的这一要求解决了这一缺陷，并将使HQP能够利用Barclay实验室中设备的卓越性能和自旋托管能力，用于演示以前从未观察到的光，机械振动和自旋之间的耦合。实现这样的光子-声子-自旋耦合是几个国际研究小组的主要目标，巴克莱实验室的HQP将在率先实现这一目标方面处于领先地位。该设备还将使光学机械检测的磁性纳米结构的属性与世界纪录的灵敏度。这些研究将产生重大影响，并进一步加强加拿大作为新兴自旋光学力学领域的领导者的地位。如果没有所要求的设备，这种优势将随着竞争研究人员的追赶而丧失，工作的影响将严重减弱。

Optomechanical devices use light as a ruler to measure miniscule fluctuations in the position of mechanical objects. 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 to control and measure nanoscale electronic and magnetic properties of materials - spins - that are essential elements for future quantum information processing and sensing technologies. The requested funding for equipment complements NSERC Discovery, Accelerator and Strategic Partnership funding awarded to the Barclay lab in 2016 to support HQP researching spin-optomechanics, and is critically needed for these HQP to successfully complete their projects. During the past two years HQP in the Barclay lab have developed nanoscale optomechanical devices that are breakthroughs on two fronts: they have demonstrated one of the first applications of a nanoscale cavity optomechanical sensor, and have created the world’s first single crystal diamond optomechanical devices. In addition to displaying properties such as record low mechanical dissipation and high sensitivity to external forces, these devices are among the first to connect cavity optomechanics with electronic and magnetic spins. If they can be operated at low temperature and in precisely controlled magnetic and RF fields, and if their spins can be precisely addressed, they offer an unrivaled platform for optomechanically probing and controlling spin systems and will be of intense interest for quantum information processing applications. However, the apparatus needed to achieve these requirements is not currently available in the Barclay lab. This request for research tools and instruments addresses this deficiency, and will enable the exceptional performance and spin hosting ability of devices in the Barclay lab to be harnessed by HQP for demonstrations of never before observed coupling between light, mechanical vibrations, and spins. Achieving such photon-phonon-spin coupling is a major goal of several international research groups, and with the requested equipment HQP in the Barclay lab will be in a leading position to achieve this goal first. This apparatus will also enable optomechanical detection of the properties of magnetic nanostructures with world record sensitivity. Such studies will make major impacts and further strengthen Canada’s position as a leader in the emerging field of spin-optomechanics. Without the requested equipment, this advantage will be lost as competing researchers catch up, and the impact of the work will be severely diminished.
