电荷量子-原子杂化
Charge Qubit-Atom Hybrid
摘要：
研究了一个新的超导电荷量子比特与单个中性原子通过电偶极耦合直接相互作用的混合系统。宏观超导电路与微观原子系统的接口是通过改变电荷量子比特的栅极电容来实现的。为了实现强相互作用，我们采用了两个里德堡态的电偶极允许跃迁，这改变了栅极电容器的电介质的极化率。以不同速率扫描栅极电压导致混合量子态的精确控制。此外，我们展示了一个通用的两量子比特门的可能实现。
英文摘要：
We investigate a novel hybrid system of a superconducting charge qubit interacting directly with a single neutral atom via electric dipole coupling. Interfacing of the macroscopic superconducting circuit with the microscopic atomic system is accomplished by varying the gate capacitance of the charge qubit. To achieve strong interaction, we employ two Rydberg states with an electric-dipole allowed transition, which alters the polarizability of the dielectric medium of the gate capacitor. Sweeping the gate voltage with different rates leads to a precise control of hybrid quantum states. Furthermore, we show a possible implementation of a universal two-qubit gate.
