“Quantum sensing” describes the use of a quantum system, quantum properties, or quantum
phenomena to perform a measurement of a physical quantity. Historical examples of …

Superconducting circuits are macroscopic in size but have generic quantum properties such
as quantized energy levels, superposition of states, and entanglement, all of which are more …

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 …

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 …

Quantum coherence in natural and artificial spin systems is fundamental to applications
ranging from quantum information science to magnetic-resonance imaging and …

Superconducting circuits can behave like atoms making transitions between two levels.
Such circuits can test quantum mechanics at macroscopic scales and be used to conduct …

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 …

Dielectric loss from two-level states is shown to be a dominant decoherence source in
superconducting quantum bits. Depending on the qubit design, dielectric loss from …

Quantum error correction (QEC) and fault-tolerant quantum computation represent one of
the most vital theoretical aspects of quantum information processing. It was well known from …
