We found analytically a first-order quantum phase transition in a Cooper pair box array of N low-capacitance Josephson junctions capacitively coupled to resonant photons in a microwave cavity. The influence of radio-frequency microwaves on the Coulomb blockade characteristics in small Josephson junctions was studied using a one-dimensional array of ten small Al tunnel junctions in the frequency range from 1 to 1000 MHz.
Independently, exotic circuit elements that require Cooper pairs to form pairs in order to tunnel have been developed to encode and topologically protect quantum information. In this work, we demonstrate that pairing Cooper pairs magnifies the phase fluctuations of the circuit ground state. The basic building block of the Josephson junction array is the Cooper pair box [23, 24], see figure 1, consisting of a superconducting island (capacitance C) connected to a bulk (grounded) superconductor by a split Josephson junction enclosing a magnetic flux Φ.In this paper, we present experimental results on a novel single Cooper pair circuit based on a superconducting loop, which solves both the inductance and the offset charge noise problems. The small junction of our circuit is shunted by a series array of carefully chosen larger area tunnel junctions (Fig 1A-C).
The dynamics of Cooper pairs and vortices in a Josephson-junction array is investigated. For this purpose, a Hamiltonian is constructed in terms of vortex charges. Josephson-type equations for vortices are derived.
