This review describes the emerging field of waveguide quantum electrodynamics concerned
with the interaction of photons propagating in a waveguide with localized quantum emitters …

Quantum computers have made extraordinary progress over the past decade, and
significant milestones have been achieved along the path of pursuing universal fault-tolerant …

Superconducting qubits provide a promising path toward building large-scale quantum
computers. The simple and robust transmon qubit has been the leading platform, achieving …

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 …

Strongly correlated quantum systems give rise to many exotic physical phenomena,
including high-temperature superconductivity. Simulating these systems on quantum …

Mechanical resonators are emerging as an important new platform for quantum science and
technologies. A large number of proposals for using them to store, process and transduce …

Superconducting qubits in a waveguide have long-range interactions mediated by photons
that cause the emergence of collective states. Destructive interference between the qubits …

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 …
