Superconducting circuits are a competitive platform for quantum computation because they
offer controllability, long coherence times and strong interactions—properties that are …

We engineer a quantum bath that enables entropy and energy exchange with a one-
dimensional Bose-Hubbard lattice with attractive on-site interactions. We implement this in …

The paradigmatic example of a topological phase of matter, the two-dimensional Chern
insulator,,,–, is characterized by a topological invariant consisting of a single integer, the …

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

Dissipation is ubiquitous in nature and plays a crucial role in quantum systems such as
causing decoherence of quantum states. Recently, much attention has been paid to an …

The theory of electric polarization in crystals defines the dipole moment of an insulator in
terms of a Berry phase (geometric phase) associated with its electronic ground state,. This …

Scalable, coherent many-body systems can enable the realization of previously unexplored
quantum phases and have the potential to exponentially speed up information processing …

Recent years have seen tremendous progress in creating complex atomic many-body
quantum systems. One approach is to use macroscopic, effectively thermodynamic …

Quantum gases in optical lattices offer an opportunity to experimentally realize and explore
condensed matter models in a clean, tunable system. We used single atom–single lattice …

Guiding many-body systems to desired states is a central challenge of modern quantum
science, with applications from quantum computation, to many-body physics and quantum …
