Abstract :
We show that it is possible to fabricate a device, based on a superconducting nanowire, to demonstrate the existence of coherent quantum phase slip (QPS). If coherent QPS exists, this device will form the basis of a new type of quantum current standard capable of closing the metrological triangle.
