研究了利用库工程方法制备纠缠纯高斯态。特别地，我们考虑由（2 <$+1）个量子谐振子组成的链，其中链的中心振子耦合到单个库。然后，我们完全参数化的类（2 π +1）模纯高斯态，可以制备这种类型的量子谐振子链。这种参数化使我们能够确定这种量子谐振子链的稳态纠缠特性。
We study the preparation of entangled pure Gaussian states via reservoir engineering. In particular, we consider a chain consisting of (2ℵ+1) quantum harmonic oscillators where the central oscillator of the chain is coupled to a single reservoir. We then completely parametrize the class of (2ℵ+1)-mode pure Gaussian states that can be prepared by this type of quantum harmonic oscillator chain. This parametrization allows us to determine the steady-state entanglement properties of such quantum harmonic oscillator chains.
