Quantum 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...
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 کاملEnhanced Microwave Power from Triangular Arrays of Small Josephson Junctions
We report on high frequency measurements of underdamped Josephson junction arrays consisting of two rows of parallel biased cells. The rf voltage generated on the junctions transverse to the bias current (horizontal junctions) is detected by a room temperature receiver in the Wband. In order to enhance the emitted power, it has been proposed (S.P.Y.) that the single horizontal junction in each ...
متن کاملPhase transition in current-biased arrays of small Josephson junctions
We present a variational approach to treat the metastable superconducting state in an array of small Josephson junctions driven by an applied current. Using this approach, we calculate an approximate phase diagram of such an array with a current bias. Our approach is a generalization of one previously used for such an array at zero applied current. We find that, for a given array, a superconduc...
