摘要：

基于时间复用（TM）的连续变量（CV）方案是大规模量子信息处理（QIP）的主要方法之一。作为这种方法的基本构建块，需要量子光源来顺序地产生时分复用的压缩光脉冲;然而，传统的CV TM实验使用固定光源，其只能输出具有相同压缩水平和相位的压缩脉冲。我们在这里展示了一个可编程的时间复用压缩光源，可以产生连续的压缩脉冲与各种压缩水平和相位在小于100 ns的时间间隔。生成模式可以由软件任意选择而不改变其硬件配置。这通过使用波导光学参量放大器并调制其连续泵浦光来实现。我们的光源将执行各种大规模CV QIP任务。

英文摘要：

One of the leading approaches to large-scale quantum information processing (QIP) is the continuous-variable (CV) scheme based on time multiplexing (TM). As a fundamental building block for this approach, quantum light sources to sequentially produce time-multiplexed squeezed-light pulses are required; however, conventional CV TM experiments have used fixed light sources that can only output the squeezed pulses with the same squeezing levels and phases. We here demonstrate a programmable time-multiplexed squeezed light source that can generate sequential squeezed pulses with various squeezing levels and phases at a time interval below 100 ns. The generation pattern can be arbitrarily chosen by software without changing its hardware configuration. This is enabled by using a waveguide optical parametric amplifier and modulating its continuous pump light. Our light source will implement various large-scale CV QIP tasks.
