The key issue for the implementation of a metamaterial is to demonstrate the existence of
collective modes corresponding to coherent oscillations of the meta-atoms. Atoms of natural …

We introduce a frequency-multiplexed readout scheme for superconducting phase qubits.
Using a quantum circuit with four phase qubits, we couple each qubit to a separate lumped …

We construct a microwave detector based on the voltage switching of an underdamped
Josephson junction that is positioned at a current antinode of a λ/4 coplanar waveguide …

An important desired ingredient of superconducting quantum circuits is a readout scheme
whose complexity does not increase with the number of qubits involved in the measurement …

This article proposes a cryogenic inverter-based low noise amplifier (LNA) for qubit readout.
Its input impedance matching is realized by a high-ON-chip gate inductor and capacitive …

We report experiments on superconducting flux qubits in a circuit quantum electrodynamics
(cQED) setup. Two qubits, independently biased and controlled, are coupled to a coplanar …

We propose a method to assist fault mitigation in quantum computation through the use of

We describe fabrication and testing of composite flux qubits combining Nb-and Al-based
superconducting circuit technology. This hybrid approach to making qubits allows for …

(57) ABSTRACT A superconducting input and/or output system employs at least one
microwave superconducting resonator. The micro wave superconducting resonator (s) may …

We investigate the propagation of microwave photons in a one-dimensional open
waveguide interacting with a number of artificial atoms (qubits). Within the formalism of …
