标题： Magic States in the Asymmetric Quantum Rabi Model

摘要： 魔法或非稳定化是量子计算中一种资源，已在量子网络中得到了广泛研究。它描述了 Clifford 门无法生成给定状态的程度，体现了量子计算相对于经典计算的优势。然而，在连续变量和一般复合系统中的定义仍然是一个开放问题。我们研究了一个双部分系统中的魔法，即不对称量子 Rabi 模型，这是量子光学中的一个典型模型。我们探讨了在哈密顿量参数空间中量子比特约化系统中的魔法存在情况，光-物质相互作用在其生成中的作用，以及在相应玻色自由度中的 Wigner 函数负性表现。最后，我们讨论了在强耦合和超强耦合区域中魔法态制备的结果，以及其在量子信息系统中的意义。 显示英文摘要

摘要： Magic or non-stabilizerness is a resource for quantum computing that has been extensively studied in qudit networks. It describes the degree to which Clifford gates cannot generate a given state, capturing the advantage of quantum over classical computing. However, its definition in continuous variables and general composite systems remains an open issue. We study magic in a bipartite system, the Asymmetric Quantum Rabi model, a paradigmatic model from quantum optics. We explore the presence of magic in the qubit-reduced system throughout the Hamiltonian parameter space, the role of light-matter interactions in its generation, and the manifestation of Wigner function negativity in the corresponding bosonic degree of freedom. Finally, we discuss our results for magic state preparation in the strong and ultra-strong coupling regimes within the context of quantum informational systems.
