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 …

Superconducting qubits are leading candidates in the race to build a quantum computer
capable of realizing computations beyond the reach of modern supercomputers. The …

The aim of this review is to provide quantum engineers with an introductory guide to the
central concepts and challenges in the rapidly accelerating field of superconducting …

We present a comprehensive architectural analysis for a proposed fault-tolerant quantum
computer based on cat codes concatenated with outer quantum error-correcting codes. For …

The dynamics of quantum information in strongly interacting systems, known as quantum
information scrambling, has recently become a common thread in our understanding of …

Quantum information is vulnerable to environmental noise and experimental imperfections,
hindering the reliability of practical quantum information processors. Therefore, quantum …

The great promise of quantum computers comes with the dual challenges of building them
and finding their useful applications. We argue that these two challenges should be …

We demonstrate a superconducting artificial atom with strong unidirectional coupling to a
microwave photonic waveguide. Our artificial atom is realized by coupling a transmon qubit …

Graph states are a broad family of entangled quantum states, each defined by a graph
composed of edges representing the correlations between subsystems. Such states …

While designing the energy-momentum relation of photons is key to many linear, nonlinear,
and quantum optical phenomena, a new set of light-matter properties may be realized by …
