论文摘要
杂种量子系统中量子信息的转移和存储，由原子或与腔相互作用的旋转组成的量子信息受到旋转的不均匀性的不利影响，这抵消了物理成分之间的激发的连贯交换。我们使用基于变异重新归化组的完整量子处理，我们展示了如何在参数驱动的混合系统状态中编码的量子信息受到强烈保护，以防止由于旋转谐振中的不均匀性而产生的任何抗碳性。
The transfer and storage of quantum information in a hybrid quantum system, consisting of an ensemble of atoms or spins interacting with a cavity, is adversely affected by the inhomogeneity of the spins, which negates the coherent exchange of excitations between the physical components. Using a full quantum treatment based on variational renormalization group, we show how quantum information encoded in the states of a parametrically driven hybrid system is strongly protected against any decoherence that may arise due to the inhomogeneity in the spin-ensemble.
