摘要:

基于测量的量子计算通过对大纠缠团簇态的简单测量提供了指数级的计算速度。我们提出并证明了一个可扩展的方案,适用于通用的基于测量的量子计算的光子簇态的产生。我们利用压缩光模式,延迟环,和分束器变换的时间复用确定性地产生一个圆柱形的集群状态的二维(2D)拓扑结构所需的通用量子信息处理。所产生的状态由超过30000纠缠模式排列在一个圆柱形晶格与24模式的圆周上,定义输入寄存器,和1250模式的长度,定义计算深度。我们所展示的二维团簇态源可以与量子纠错相结合,以实现容错量子计算。

英文摘要:

Measurement-based quantum computation offers exponential computational speed-up via simple measurements on a large entangled cluster state. We propose and demonstrate a scalable scheme for the generation of photonic cluster states suitable for universal measurement-based quantum computation. We exploit temporal multiplexing of squeezed light modes, delay loops, and beam-splitter transformations to deterministically generate a cylindrical cluster state with a two-dimensional (2D) topological structure as required for universal quantum information processing. The generated state consists of more than 30000 entangled modes arranged in a cylindrical lattice with 24 modes on the circumference, defining the input register, and a length of 1250 modes, defining the computation depth. Our demonstrated source of 2D cluster states can be combined with quantum error correction to enable fault-tolerant quantum computation.
