Quantum information processing relies on the precise control of non-classical states in the
presence of many uncontrolled environmental degrees of freedom. The interactions …

Interacting many-body quantum systems show a rich array of physical phenomena and
dynamical properties, but are notoriously difficult to study: they are analytically challenging …

The efficient simulation of quantum systems is a primary motivating factor for developing
controllable quantum machines. For addressing systems with underlying bosonic structure, it …

Superconducting circuits based on Josephson junctions are regarded as one of the most
promising technologies for the implementation of scalable quantum computers. This review …

Superconducting qubits seem promising for useful quantum computers, but the currently
wide-spread qubit designs and techniques do not yet provide high enough performance …

We investigate critical quantum metrology, that is, the estimation of parameters in many-
body systems close to a quantum critical point, through the lens of Bayesian inference …

Lattices with dispersionless, or flat, energy bands have attracted substantial interest in part
due to the strong dependence of particle dynamics on interactions. Using superconducting …

Particle transport and localization phenomena in condensed-matter systems can be
modeled using a tight-binding lattice Hamiltonian. The ideal experimental emulation of such …

Superconducting quantum processors are a compelling platform for analogue quantum
simulation due to the precision control, fast operation and site-resolved readout inherent to …

We demonstrate nonequilibrium steady-state photon transport through a chain of five
coupled artificial atoms simulating the driven-dissipative Bose-Hubbard model. Using …
