我们提出一种自主方案，通过辅助量子比特弛豫校正反杰恩斯-卡明斯（anti-Jaynes-Cummings）相互作用，以稳定克尔腔（Kerr cavity）中指定的福克态（Fock states）。全林德布拉德（Lindblad）模拟显示，稳态由福克态|1⟩至|4⟩主导，伴随显著的维格纳负性（Wigner negativity）。解析生灭模型（birth-death model）捕捉了稳态布居数，并确定了稳定的工作区域。这些结果确立辅助量子比特弛豫作为自主储层工程的一种资源，为在单个克尔腔中制备非经典玻色态，以及通过边界储层在克尔腔链中制备该态提供了途径。
英文摘要
We propose an autonomous scheme for stabilizing prescribed Fock states in a Kerr cavity by rectifying anti-Jaynes--Cummings interactions with auxiliary-qubit relaxation. Full Lindblad simulations demonstrate steady states dominated by the Fock states $|1\rangle$ through $|4\rangle$, accompanied by pronounced Wigner negativity. An analytical birth--death model captures the steady-state populations and identifies the operating regime for stabilization. These results establish auxiliary-qubit relaxation as a resource for autonomous reservoir engineering and provide a route to nonclassical bosonic-state preparation in a single Kerr cavity and, through a boundary reservoir, in a Kerr-cavity chain.
