BACKGROUND The past two decades have seen intense efforts aimed at building quantum
computing hardware with the potential to solve problems that are intractable on classical …

Advances in materials science and engineering have played a central role in the
development of classical computers and will undoubtedly be critical in propelling the …

Amorphous solids show surprisingly universal behaviour at low temperatures. The
prevailing wisdom is that this can be explained by the existence of two-state defects within …

Current state-of-the-art superconducting microwave qubits are cooled to extremely low
temperatures to avoid sources of decoherence. Higher qubit operating temperatures would …

We report on long-term measurements of a highly coherent, nontunable superconducting
transmon qubit, revealing low-frequency burst noise in coherence times and qubit transition …

Superconducting qubit lifetimes must be both long and stable to provide an adequate
foundation for quantum computing. This stability is imperiled by two-level systems (TLSs) …

The progress witnessed within the field of quantum computing has been enabled by the
identification and understanding of interactions between the state of the quantum bit (qubit) …

Superconducting integrated circuits have demonstrated a tremendous potential to realize
integrated quantum computing processors. However, the downside of the solid-state …

A major issue for the implementation of large-scale superconducting quantum circuits is the
interaction with interfacial two-level system (TLS) defects that lead to qubit parameter …

We demonstrate that a high kinetic inductance disordered-superconductor nanowire can
realize a circuit element–known as a superinductor–with a characteristic impedance greater …
