As quantum processors grow in complexity, attention is moving to the scaling prospects of
the entire quantum computing system, including the classical support hardware. Recent …

Technologies that rely on quantum bits (qubits) require long coherence times and high-
fidelity operations. Superconducting qubits are one of the leading platforms for achieving …

We benchmark the decoherence of superconducting transmon qubits to examine the
temporal stability of energy relaxation, dephasing, and qubit transition frequency. By …

In order to understand the emergence of superconductivity it is useful to study the reverse
process and identify the various pathways that lead to its destruction. One way is to increase …

Superconducting qubits are a leading system for realizing large-scale quantum processors,
but overall gate fidelities suffer from coherence times limited by microwave dielectric loss …

We summarize the recent progress of the Axion Longitudinal Plasma Haloscope (ALPHA)
Consortium, a new experimental collaboration to build a plasma haloscope to search for …

Nonequilibrium quasiparticle excitations degrade the performance of a variety of
superconducting circuits. Understanding the energy distribution of these quasiparticles will …

As quantum coherence times of superconducting circuits have increased from nanoseconds
to hundreds of microseconds, they are currently one of the leading platforms for quantum …

Error-corrected quantum computers can only work if errors are small and uncorrelated. Here,
I show how cosmic rays or stray background radiation affects superconducting qubits by …
