论文摘要
量子信息处理器的快速发展加速了对量子网络的技术需求。一种有希望的方法使用机械谐振器作为微波和光场之间的中介。然后可以将来自超导，拓扑或自旋量子置换处理器的信号连贯地转换为电信波长处的光态。但是，目前由均匀结构构建的设备具有增加的噪声和较小的转换效率。将不同材料的优势特性与异质设计相结合，应允许进行优质的量子转导设备 - 到目前为止，这些混合方法已经受到复杂的制造程序的阻碍。在这里，我们提出了一种基于以前的挑选想法的新颖集成方法，可以将不同材料的独立设备组件结合到单个设备中。该方法允许通过在此过程中连续的光学监视来精确对齐。使用我们的方法，我们组装了具有最新波长转换特性的混合硅硅甲酸酯装置。
The rapid development of quantum information processors has accelerated the demand for technologies that enable quantum networking. One promising approach uses mechanical resonators as an intermediary between microwave and optical fields. Signals from a superconducting, topological, or spin qubit processor can then be converted coherently to optical states at telecom wavelengths. However, current devices built from homogeneous structures suffer from added noise and small conversion efficiency. Combining advantageous properties of different materials into a heterogeneous design should allow for superior quantum transduction devices -- so far these hybrid approaches have however been hampered by complex fabrication procedures. Here we present a novel integration method based on previous pick-and-place ideas, that can combine independently fabricated device components of different materials into a single device. The method allows for precision alignment by continuous optical monitoring during the process. Using our method, we assemble a hybrid silicon-lithium niobate device with state-of-the-art wavelength conversion characteristics.
