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 nontrivial multipartite entangled states such as cluster states suitable for measurement-based quantum computation.

高斯纠缠态单点挤压油藏的耗散工程。

我们研究了在玻色子晶格模型中多体纠缠高斯态的耗散制备，这可能与量子技术的应用有关。我们假设资源最少，由具有单个局部压缩储层的守恒二次哈密顿量表示的系统表示。我们表明，通过这种方式，可以在稳态下准备各种各样的纯态，这些纯态可以通过对一组相同压缩的模式应用通用无源高斯变换来生成。这包括非平凡的多部分纠缠态，例如适合基于测量的量子计算的簇态。
