论文摘要
空腔雄伟提供了一个容易控制的混合系统，该系统由腔模式，镁模式和声子模式组成，用于量子状态操作。为了在混合光子磁子模式和声子模式之间实现快速抗压状态的转移，我们根据反过渡量子驾驶的反糖汉密尔顿和Levis-Riesenfeld不变的不变型逆向工程提出了两个加速的绝热通用协议。相反的汉密尔顿和利维斯 - 里森菲尔德不变的都通常适用于具有任意目标状态的连续变量系统。有趣的是，可以根据创建和歼灭操作员而不是系统 - 元素及其时间衍生物来构建我们的抵绝热哈密顿量。我们的协议可以针对稳定性进行优化，以针对系统耦合强度和频率失调的系统误差。它有助于光子和宏伟量子信息的量子记忆。我们还讨论了耗散和反旋转相互作用的影响。
Cavity magnomechanics provides a readily-controllable hybrid system, that consisted of cavity mode, magnon mode, and phonon mode, for quantum state manipulation. To implement a fast-and-robust state transfer between the hybrid photon-magnon mode and the phonon mode, we propose two accelerated adiabatic-passage protocols individually based on the counterdiabatic Hamiltonian for transitionless quantum driving and the Levis-Riesenfeld invariant for inverse engineering. Both the counterdiabatic Hamiltonian and the Levis-Riesenfeld invariant generally apply to the continuous-variable systems with arbitrary target states. It is interesting to find that our counterdiabatic Hamiltonian can be constructed in terms of the creation and annihilation operators rather than the system-eigenstates and their time-derivatives. Our protocol can be optimized with respect to the stability against the systematic errors of coupling strength and frequency detuning. It contributes to a quantum memory for photonic and magnonic quantum information. We also discuss the effects from dissipation and the counter-rotating interactions.
