摘要：
We have studied dynamics of single Cooper pairs and vortices in networks of small area aluminum tunnel junctions. In this paper we report on two experiments: a demonstration of the Heisenberg uncertainty relation between the number of Cooper pairs and the phase of the superconducting order parameter and new measurements that seem to indicate band-like behavior of vortices in a one-dimensional array.
