The performance of superconducting circuits for quantum computing is limited by materials
losses. In particular, coherence times are typically bounded by two-level system (TLS) …

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 …

It has long been recognized that atomic emission of radiation is not an immutable property of
an atom, but is instead dependent on the electromagnetic environment and, in the case of …

We construct quantum circuits that exactly encode the spectra of correlated electron models
up to errors from rotation synthesis. By invoking these circuits as oracles within the recently …

We have integrated single and coupled superconducting transmon qubits into flip-chip
modules. Each module consists of two chips—one quantum chip and one control chip—that …

Quantum computing is considered as a next-generation information processing technology.
The basic element of a quantum computing system is a quantum bit, often called a qubit …

Entanglement is a key resource in quantum computing and other prospective technologies.
Multidimensional photonic graph states, such as cluster states, have a special entanglement …

As superconducting qubit circuits become more complex, addressing a large array of qubits
becomes a challenging engineering problem. Dense arrays of qubits benefit from, and may …

We report high qubit coherence as well as low cross-talk and single-qubit gate errors in a
superconducting circuit architecture that promises to be tileable to two-dimensional (2D) …

High-fidelity gate operations are essential to the realization of a fault-tolerant quantum
computer. In addition, the physical resources required to implement gates must scale …
