The quantization scheme between double enhanced charge phase-slip (ECPS) qubits is given. In this system, there exist quantum entanglement phenomenona. The entanglement characteristic is discussed by employing the concurrence. An interesting conclusion is obtained, i.e., if one desire to change the entanglement between two ECPS qubits, the mutual inductance should be considered first, but it is also a good choice to tune symmetric and asymmetric combination of two gate voltages.

双增强电荷相滑量子比特的量化和量子纠缠控制

给出了双增强电荷相滑（ECPS）量子位之间的量化方案。在这个系统中，存在量子纠缠现象a。利用并发性讨论了纠缠特性。得到了一个有趣的结论，即如果想要改变两个 ECPS 量子位之间的纠缠，应该首先考虑互感，但调整两个栅极电压的对称和不对称组合也是一个不错的选择。
