We show that the physics underlying the dynamical Casimir effect may generate multipartite quantum correlations. To achieve it, we propose a circuit quantum electrodynamics scenario involving superconducting quantum interference devices, cavities, and superconducting qubits, also called artificial atoms. Our results predict the generation of highly entangled states for two and three superconducting qubits in different geometric configurations with realistic parameters. This proposal paves the way for a scalable method of multipartite entanglement generation in cavity networks through dynamical Casimir physics.
我们表明，动力学 Casimir 效应背后的物理原理可能产生多部分量子相关。为了实现这一点，我们提出了一个涉及超导量子干涉器件、腔和超导量子比特（也称为人工原子）的电路量子电动力学场景。我们的结果预测了在不同几何构型和现实参数下，两个和三个超导量子比特产生高度纠缠态的情况。该方案为通过动力学 Casimir 物理在腔网络中产生多部分纠缠的可扩展方法铺平了道路。
