Abstract

We propose a type of nonadiabatic scheme to detect the geometric phase for the macroscopic state of a Josephson-junction system. After extending the scheme to the two-qubit cases, we provide a type of nonadiabatic geometric C-NOT gate that can play an important role in quantum computation.
