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 improve the quality of quantum circuits on superconducting quantum computing
systems, as measured by the quantum volume (QV), with a combination of dynamical …

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

Sharing information coherently between nodes of a quantum network is fundamental to
distributed quantum information processing. In this scheme, the computation is divided into …

Quantum superpositions of distinct coherent states in a single-mode harmonic oscillator,
known as “cat states,” have been an elegant demonstration of Schrödinger's famous cat …

The design of quantum hardware that reduces and mitigates errors is essential for practical
quantum error correction (QEC) and useful quantum computation. To this end, we introduce …

High-fidelity and rapid readout of a qubit state is key to quantum computing and
communication, and it is a prerequisite for quantum error correction. We present a readout …

Superconducting qubits typically use a dispersive readout scheme, where a resonator is
coupled to a qubit such that its frequency is qubit-state dependent. Measurement is …

Quantum batteries are miniature energy storage devices and play a very important role in
quantum thermodynamics. In recent years, quantum batteries have been extensively …

Quantum computers are traditionally operated by programmers at the granularity of a gate-
based instruction set. However, the actual device-level control of a quantum computer is …
