项目摘要

Optomechanical devices couple light to the motion of mechanical resonators, and are central to seminal observations of fundamental phenomena spanning nano- to macroscopic scales. An example of the latter is the spectacular observation of gravitational waves by LIGO. At the nanoscale, optomechanical devices have recently enabled the first observation of a mechanical resonator that is laser cooled to its quantum mechanical ground state, where quantum effects influence its mechanical motion. ** Nanoscale quantum optomechanical devices also have tremendous practical potential. They are particularly suited for sensing applications that convert a force or field into motion of a mechanical oscillator. However, to date, a quantum limited optomechanical device has never been used for such applications. This is in part due to the technical challenges associated with creating optomechanical devices that are sufficiently isolated from noise for quantum effects to limit their performance, and in part due to the difficulty of connecting these devices to conventional fiber or free-space optical components and measurement tools.** This proposal describes a partnership to solve these challenges, by building upon unique and world-leading nanofabrication and experimental capabilities developed by the applicants and an industrial partner during the past three years. It will develop and demonstrate optomechanical devices whose sensitivity to quantum effects is harnessed for sensing applications, and will solve the critical problems preventing the adoption of these devices by the broader optical and nanomechanical sensor communities. En-route to developing these devices, nanofabrication and device integration technology will be developed that can be applied to a wide range of quantum platforms. This includes cryogenic technology and diamond based components of interest to the team's industrial partner. Devices developed during this project will also be used to for spin-phonon transduction and actuation, and as nanomagnetic sensors. These devices will advance development of quantum technology, an emerging field that has significant potential to dramatically impact Canada's economy.**********************************************

光力学设备将光线与机械谐振器的运动相对，并且是跨纳米 - 宏观尺度的基本现象的核心观测。后者的一个例子是Ligo对重力波的壮观观察。在纳米级，光机械设备最近使对机械谐振器的首次观察到了激光器，该机械谐振器将其冷却至其量子机械基态，其中量子效应会影响其机械运动。 **纳米级量子光机械设备也具有巨大的实用潜力。它们特别适合传感将力或场转换为机械振荡器运动的应用。但是，迄今为止，量子有限的光学设备从未用于此类应用。这部分是由于与创建与噪声相比足够隔离的量子效应以限制其性能的技术挑战所带来的技术挑战，部分原因是将这些设备连接到传统的光纤或自由空间的光学光学组件和测量工具的困难。工业合作伙伴在过去三年中。它将开发和展示其对量子效应的敏感性用于感应应用的光学机械设备，并将解决关键问题，以防止更广泛的光学和纳米力学传感器群落采用这些设备。将开发开发这些设备，纳米型和设备集成技术的路线，可以应用于广泛的量子平台。这包括对团队工业合作伙伴感兴趣的低温技术和基于钻石的组件。该项目期间开发的设备也将用于自旋传输和驱动，并用作纳米磁传感器。这些设备将推进量子技术的开发，这是一个新兴领域，具有巨大的潜力，可以极大地影响加拿大的经济。*************************************************************
