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 …

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 technological world is in the midst of a quantum computing and quantum information
revolution. Since Richard Feynman's famous 'plenty of room at the bottom'lecture (Feynman …

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

Superconducting fluxonium qubits provide a promising alternative to transmons on the path
toward large-scale superconductor-based quantum computing due to their better coherence …

Statistical mechanics is founded on the assumption that all accessible configurations of a
system are equally likely. This requires dynamics that explore all states over time, known as …

Faster and more accurate state measurement is required for progress in superconducting
qubit experiments with greater numbers of qubits and advanced techniques such as …

Quantum emulators, owing to their large degree of tunability and control, allow the
observation of fine aspects of closed quantum many-body systems, as either the regime …

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) …
