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 …

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 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 …

The scalable application of quantum information science will stand on reproducible and
controllable high-coherence quantum bits (qubits). Here, we revisit the design and …

When ultralight axion dark matter encounters a static magnetic field, it sources an effective
electric current that follows the magnetic field lines and oscillates at the axion Compton …

The efficiency of the future devices for quantum information processing is limited mostly by
the finite decoherence rates of the individual qubits and quantum gates. Recently …

Superconducting qubits are electronic circuits comprising lithographically defined
Josephson tunnel junctions, inductors, capacitors, and interconnects. When cooled to …

The magnetic sensing at nanoscale level is a promising and interesting research topic of
nanoscience. Indeed, magnetic imaging is a powerful tool for probing biological, chemical …

We study the impact of low-frequency magnetic flux noise upon superconducting transmon
qubits with various levels of tunability. We find that qubits with weaker tunability exhibit …

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