Quantum-mechanical effects at the macroscopic level were first explored in Josephson-
junction-based superconducting circuits in the 1980s. In recent decades, the emergence of …

In this short review article, we aim to provide physicists not working within the quantum
computing community a hopefully easy-to-read introduction to the state of the art in the field …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

Active quantum error correction using qubit stabilizer codes has emerged as a promising,
but experimentally challenging, engineering program for building a universal quantum …

The promise of single Cooper-pair quantum circuits based on tunnel junctions for metrology
and quantum information applications is severely limited by the influence of offset charges …

Recent progress in solid-state quantum information processing has stimulated the search for
amplifiers and frequency converters with quantum-limited performance in the microwave …

Breaking time-reversal symmetry is a prerequisite for accessing certain interesting many-
body states such as fractional quantum Hall states. For polaritons, charge neutrality prevents …

The future development of quantum information using superconducting circuits requires
Josephson qubits with long coherence times combined with a high-fidelity readout …

Superconducting coplanar waveguide (SCPW) resonators have a wide range of
applications due to the combination of their planar geometry and high quality factors relative …

We review the theory, fabrication, and implementation of the Josephson bifurcation amplifier
(JBA). At the core of the JBA is a nonlinear oscillator based on a reactively shunted …
