论文摘要
我们研究了可能与量子技术应用相关的多体纠缠高斯州的多体纠缠高斯州的耗散制备。我们假设最少的资源是由粒子持有的二次汉密尔顿人描述的系统，并带有一个局部挤压储层。我们表明，以这种方式，可以在稳定状态下准备可以通过在一组同样挤压模式上应用通用的被动高斯转换来生成的宽类纯状态。这包括非平凡的多部分纠缠状态，例如适合基于测量的量子计算的群集状态。
We study the dissipative preparation of many-body entangled Gaussian states in bosonic lattice models which could be relevant for quantum technology applications. We assume minimal resources, represented by systems described by particle-conserving quadratic Hamiltonians, with a single localized squeezed reservoir. We show that in this way it is possible to prepare, in the steady state, the wide class of pure states which can be generated by applying a generic passive Gaussian transformation on a set of equally squeezed modes. This includes non-trivial multipartite entangled states such as cluster states suitable for measurement-based quantum computation.
