我们展示了如何利用相对论运动在腔模中产生连续变化的高斯团簇态。我们的研究结果可以用超导电路的实验证明，其中可调边界条件对应于以接近光速的速度移动的反射镜。特别是，我们提出了一个四方形集群状态的生成作为第一个例子，可以很容易地在实验室中实现。由于团簇态是通用单向量子计算的通用资源，我们的结果为相对论量子计算方案铺平了道路。
We show how to use relativistic motion to generate continuous variable Gaussian cluster states within cavity modes. Our results can be demonstrated experimentally using superconducting circuits where tuneable boundary conditions correspond to mirrors moving with velocities close to the speed of light. In particular, we propose the generation of a quadripartite square cluster state as a first example that can be readily implemented in the laboratory. Since cluster states are universal resources for universal one-way quantum computation, our results pave the way for relativistic quantum computation schemes.
