论文摘要
作用于一对Qubit的一个共同环境会导致多种不同现象,例如产生Qubit Qubit纠缠,量子同步和次级次级。在这里,我们定义了纠缠产生,量子同步和次级的时间无关的图形,并对它们对模型参数的依赖性进行了广泛的分析和数值研究。我们还谈到了最近提出的对浴室驱动的动态的集体性的衡量标准,并发现它几乎完美地见证了纠缠产生的行为。我们的结果表明,在一般情况下,同步和次级可以用作纠缠公共浴的可靠局部签名。最后,我们提出了基于两个转速量子位与通用电阻器的两个transmon速度机的实验实现,该电阻在任何制度中都提供了开放系统的多功能量子仿真平台。
A common environment acting on a pair of qubits gives rise to a plethora of different phenomena, such as the generation of qubit-qubit entanglement, quantum synchronization and subradiance. Here we define time-independent figures of merit for entanglement generation, quantum synchronization and subradiance, and perform an extensive analytical and numerical study of their dependence on model parameters. We also address a recently proposed measure of the collectiveness of the dynamics driven by the bath, and find that it almost perfectly witnesses the behavior of entanglement generation. Our results show that synchronization and subradiance can be employed as reliable local signatures of an entangling common-bath in a general scenario. Finally, we propose an experimental implementation of the model based on two transmon qubits capacitively coupled to a common resistor, which provides a versatile quantum simulation platform of the open system in any regime.
