摘要:

在量子计算的各种方法中,基于测量的量子计算(MBQC)在时域中复用是目前解决可扩展性需求的一种有前途的方法。MBQC需要两个组件:集群状态和可编程测量。通过时域复用,前者已经在超大规模上实现。然而,后者仍未实现,使得大规模集群状态未被使用。在这项工作中,我们做了这样一个测量系统,并用它来演示基本的量子操作复用在时域与25 MHz的时钟频率。我们验证的输入状态和它们的非经典性的单步量子操作的转换,也观察到多步量子操作多达一百步。

英文摘要:

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.
