光子平台是实现多种量子通信协议和量子模拟实验的一种很有前途的技术。此外，大规模集成干涉仪最近在量子计算中发挥了相关作用，特别是在玻色子采样设备和量子霸权的竞争中。事实上，已经提出了各种线性光学方案来实现酉变换，每一个都适合于特定的任务。尽管如此，迄今仍缺乏在更广泛和现实条件下对技术状况的全面分析。在目前的工作中，我们填补了这一空白，在一个统一的框架中提供了三种主要光子结构的定量比较，即三角形和方形设计以及所谓的快速转换。在存在损耗和内部反射率和相位控制不完善的情况下，对所有布局进行了分析，表明方形设计在大多数操作条件下优于三角形方案。我们的结果代表了在大规模集成光子器件上实现量子信息协议的又一步。
Photonic platforms represent a promising technology for the realization of several quantum communication protocols and for experiments of quantum simulation. Moreover, large-scale integrated interferometers have recently gained a relevant role in quantum computing, specifically with Boson Sampling devices and the race for quantum supremacy. Indeed, various linear optical schemes have been proposed for the implementation of unitary transformations, each one suitable for a specific task. Notwithstanding, so far a comprehensive analysis of the state of the art under broader and realistic conditions is still lacking. In the present work we fill this gap, providing in a unified framework a quantitative comparison of the three main photonic architectures, namely the ones with triangular and square designs and the so-called fast transformations. All layouts have been analyzed in presence of losses and imperfect control over the internal reflectivities and phases, showing that the square design outperforms the triangular scheme in most operational conditions. Our results represent a further step ahead towards the implementation of quantum information protocols on large-scale integrated photonic devices.
