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 …

In the past 20 years, impressive progress has been made both experimentally and
theoretically in superconducting quantum circuits, which provide a platform for manipulating …

During the last ten years, superconducting circuits have passed from being interesting
physical devices to becoming contenders for near-future useful and scalable quantum …

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 mechanics provides a highly accurate description of a wide variety of physical
systems. However, a demonstration that quantum mechanics applies equally to macroscopic …

Short dephasing times pose one of the main challenges in realizing a quantum computer.
Different approaches have been devised to cure this problem for superconducting qubits, a …

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 …

Superconducting circuits based on Josephson junctions exhibit macroscopic quantum
coherence and can behave like artificial atoms. Recent technological advances have made …

The act of measurement bridges the quantum and classical worlds by projecting a
superposition of possible states into a single (probabilistic) outcome. The timescale of this …

The superposition principle is a fundamental tenet of quantum mechanics. It allows a
quantum system to be 'in two places at the same time', because the quantum state of a …
