Abstract

Recent developments in quantum computing and the growing interest in optomechanics and quantum optics need platforms that enable rapid prototyping and scalability. This can be fulfilled by on-chip integration, as we present here. The different nanofabrication steps are explained, and our automated measurement setup is discussed. We present an opto-electromechanical device, the H-resonator, which enables optomechanical experiments such as electrostatic springs and nonlinearities and thermomechanical squeezing. Moreover, it also functions as an optomechanical phase shifter, an essential element for our integrated quantum optics efforts. Besides this, the equivalent of a beam splitter in photonics-the directional coupler-is shown. Its coupling ratio can be reliably controlled, as we show with experimental data. Several directional couplers combined can realize the CNOT operation with almost ideal fidelity.

片上量子光学与集成光力学
量子计算的最新发展以及对光学力学和量子光学日益增长的兴趣需要能够实现快速原型设计和可扩展性的平台。这可以通过片上集成来实现,正如我们在这里介绍的那样。解释了不同的纳米制造步骤,并讨论了我们的自动测量装置。我们提出了一种光机电设备,即H谐振器,它可以进行光机械实验,如静电弹簧、非线性和热机械挤压。此外,它还起到光学机械移相器的作用,这是我们集成量子光学工作的基本元件。除此之外,还展示了光子学中分束器的等效物——定向耦合器。实验数据表明,它的耦合比可以可靠地控制。几个定向耦合器组合在一起可以以几乎理想的保真度实现CNOT操作。
