论文摘要
可重新配置的线性光学网络是NISQ时代及以后开发光学量子信息处理平台的关键组成部分。我们报告了基于创新设计的这种设备的实现，该设计使用多模纤维的模式混合与SLM的可编程波前形状结合使用。在经典制度中探索了平台的功能。对于最多8个输入和创纪录的38个输出，我们的保真度超过93％，损失低于6.5db。该设备是在标准服务器机架内构建的，以允许现实世界使用，并在10天的时间内显示出2x8电路的一致性，而无需重新校准。
Reconfigurable linear optical networks are a key component for the development of optical quantum information processing platforms in the NISQ era and beyond. We report the implementation of such a device based on an innovative design that uses the mode mixing of a multimode fiber in combination with the programmable wavefront shaping of a SLM. The capabilities of the platform are explored in the classical regime. For up to 8 inputs and a record number of 38 outputs, we achieve fidelities in excess of 93%, and losses below 6.5dB. The device was built inside a standard server rack to allow for real world use and shows consistent performance for 2x8 circuits over a period of 10 days without re-calibration.
