论文摘要
我们开发了一个一般的理论框架，以从频率炸弹发射中动态工程量子相关性，从波导中的一系列超导码头，严格地考虑了量子共振频率的时间调制。我们证明，当两个量子位的谐振频率定期调制时，可以通过$π$相移调制时，就可以在不同侧带的散射光子的互相关中同时实现同时的束束和抗抗激素。我们的方法基于具有不同平价对称性的量子激发之间的动态转换，这是非常普遍的。它可用于控制通用动态调制量子系统中的两粒子相关性。
We develop a general theoretical framework to dynamically engineer quantum correlations in the frequency-comb emission from an array of superconducting qubits in a waveguide, rigorously accounting for the temporal modulation of the qubit resonance frequencies. We demonstrate, that when the resonance frequencies of the two qubits are periodically modulated with a $π$ phase shift, it is possible to realize simultaneous bunching and antibunching in cross-correlations of the scattered photons from different sidebands. Our approach, based on the dynamical conversion between the quantum excitations with different parity symmetry, is quite universal. It can be used to control two-particle correlations in generic dynamically modulated dissipative quantum systems.
