论文摘要
在量子计算的各种方法中，基于测量的量子计算（MBQC）在时域中多路复用是一种有前途的方法，可以解决可伸缩性的需求。 MBQC需要两个组件：群集状态和可编程测量。随着时间域的多路复用，前者已经在超大尺度上实现。然而，后者仍然没有实现，使大型集群国家未使用。在这项工作中，我们制作了这样的测量系统，并使用它来演示以25 MHz时钟频率在时域中多路复用的基本量子操作。我们验证输入状态及其非经典性的转换单步量子操作，还可以观察到多达一百个步骤的多步量子操作。
Among various approaches toward quantum computation, measurement-based quantum computation (MBQC) multiplexed in time domain is currently a promising method for addressing the need for scalability. MBQC requires two components: cluster states and programmable measurements. With time-domain multiplexing, the former has been realized on an ultra-large-scale. The latter, however, has remained unrealized, leaving the large-scale cluster states unused. In this work, we make such a measurement system and use it to demonstrate basic quantum operations multiplexed in the time domain with 25 MHz clock frequency. We verify transformations of the input states and their nonclassicalities for single-step quantum operations and also observe multi-step quantum operations up to one hundred steps.
