无序超导体中相干量子相位滑移(CQPS)的证明为探索超导体的基本电荷-相二象性开辟了一条新的途径，有望开发出具有新功能的器件和基于CQPS的强大的量子电流标准。在这里，我们演示了一种集成了几个CQPS结的器件：电荷量子干涉器件。电荷量子干涉装置成为著名的超导量子干涉装置的对偶，是Aharonov-Casher效应在无介质势垒的连续超导系统中的表现。
The demonstration of coherent quantum phase slips (CQPS) in disordered superconductors has opened up a new route towards exploring the fundamental charge-phase duality in superconductors, with the promise of devices with new functionalities and a robust quantum current standard based on CQPS. Here we demonstrate a device that integrates several CQPS junctions: the charge quantum interference device. The charge quantum interference device becomes the dual of the well-known superconducting quantum interference device, and is a manifestation of the Aharonov-Casher effect in a continuous superconducting system devoid of dielectric barriers.
