Sluice, a device where Cooper pairs can be transferred controllably by tuning charge and Josephson couplings

The sluice is a device where charges can be moved fast and synchronously. As a building block it opens a way to create a metrological source of electrical current and to investigate geometric phases in quantum mechanics. The key benefits are the controllability of both the charge and phase degrees of freedom, which renders the speed of the device without sacrificing its accuracy.
