Quantum noise thermometry for bosonic Josephson junctions in the mean-field regime
Bosonic Josephson junctions can be realized by confining ultracold gases of bosons in multiwell traps and studied theoretically with the M-site Bose-Hubbard model. We show that canonical equilibrium states of the M-site Bose-Hubbard model may be approximated by mixtures of coherent states, provided the number of atoms is large and the total energy is comparable to kBT. Using this approximation,...
متن کاملQuantum Interference in Josephson Junctions
The parallelism between diffraction and interference in optics and quantum interference in Josephson junctions is discussed and studied in details. The interdisciplinary character of the present work is highlighted through specific examples. The Fraunhofer-like pattern of the maximum Josephson current in a single Josephson junction and the periodic field dependence of the critical current in tw...
متن کاملSmall-capacitance Josephson Junctions: One-dimensional Arrays and Single Junctions
Small-capacitance superconducting tunnel junctions provide an ideal system for studying the interplay between the Josephson phase and the charge on the junction electrode, which are quantum mechanically conjugate to each other. This interplay can be probed through the superconductor-insulator (SI) transition [1], which is a quantum phase transition occurring at T = 0. The SI transition has been...
متن کاملNon-Abelian phases, pumping, and quantum computation with Josephson junctions
Non-Abelian phases can be generated in certain networks of Josephson junctions. Here we explicitely construct such a device and show how it can be applied both for adiabatic pumping and as an implementation of a quantum computer. If a quantum system is prepared in a superposition of two states, a physical observable associated with this system can exhibit oscillatory behavior depending on the r...
متن کاملQuantum Manipulations of Small Josephson Junctions
Low-capacitance Josephson junction arrays in the parameter range where single charges can be controlled are suggested as possible physical realizations of the elements which have been considered in the context of quantum computers. We discuss single and multiple quantum bit systems. The systems are controlled by applied gate voltages, which also allow the necessary manipulation of the quantum s...
