摘要
集成光子学是光学量子计算的一项关键技术。通用的、相位稳定的、可重构的多模干涉仪（量子光子处理器）能够操控光子量子态，并且是各种架构中光子量子计算机的主要组件之一。在本文中，我们报道了迄今最大的量子光子处理器的实现。该处理器可对其 20 个输入模式实现任意酉变换，对于 Haar 随机矩阵和置换矩阵分别具有 F_{\text{Haar}} = 97.4% 和 F_{\text{Perm}} = 99.5% 的振幅保真度，所有模式平均的光学损耗为 2.9 dB，以及具有 V_{\text{HOM}}=98% 的高可见度量子干涉。该处理器在 Si_3N_4 波导中实现，并由珀耳帖元件主动冷却。
