论文摘要
由于其稳定性和可扩展性，光子综合电路（PIC）有望在正在进行的第二个量子革命中发挥重要作用。尽管如此，可用的PIC平台仍需要进行重大升级，以满足量子设备的苛刻要求。在本文中，我们介绍了我们最近在将非常规的硅光子平台升级到此类目标方面的进展，包括超低传播损失，低纤维耦合损失，超导元素的整合，法拉第旋转器的整合，法拉第旋转器，快速有效的检测器以及低损耗和低能量的相位调节器，以及低能量和/或低能量的调节器。我们在两个主要应用中显示了我们的发展和视力的相关性：量子密钥分布 - 以实现更高的密钥速率和大规模部署（和低温量子计算机），以用光纤代替与低温恒温器的电连接。
Photonic integrated circuits (PICs) are expected to play a significant role in the ongoing second quantum revolution, thanks to their stability and scalability. Still, major upgrades are needed for available PIC platforms to meet the demanding requirements of quantum devices. In this paper, we present a review of our recent progress in upgrading an unconventional silicon photonics platform towards such goal, including ultra-low propagation losses, low fibre coupling losses, integration of superconducting elements, Faraday rotators, fast and efficient detectors, as well as phase modulators with low loss and/or low energy consumption. We show the relevance of our developments and of our vision in two main applications: quantum key distribution - to achieve significantly higher key rates and large-scale deployment - and cryogenic quantum computers - to replace electrical connections to the cryostat with optical fibres.
