论文摘要
我们提出了一个简洁明了的协议，以基于Floquet Engineering，在由超导量子组组成的混合系统中生成正午状态。特别是，我们根据Qubit谐振器的相互作用和镁频率，根据Qubit状态构建了三种连续变量模式的手性变化模式的损坏的哈密顿量。然后，可以通过典型的准备和测量程序来生成任意的宏伟的中午状态。我们分析了协议对量子轴耦合强度，浮力驱动强度，磁子的频率不匹配以及反旋转相互作用中系统误差的鲁棒性。我们可以在所有组件上存在量子耗散的情况下获得高保真状态。
We propose a concise and deterministic protocol to generate NOON states in a hybrid system consisting of a superconducting qubit, a circuit resonator mode, and two magnonic modes, based on Floquet engineering. In particular, we construct a time-reversal-symmetry broken Hamiltonian for chiral state propagation of the three continuous-variable modes depending on qubit state, by the time modulation over qubit-resonator interaction and magnon frequency. Then an arbitrary magnonic NOON state can be generated by a typical preparing-and-measurement procedure. We analyze the robustness of our protocol against the systematic errors in the qubit-magnon coupling strength, the Floquet-driving intensity, the frequency mismatch of the magnons, and the counter-rotating interactions. We can obtain a high-fidelity NOON state in the presence of the quantum dissipation on all components.
