@article{Ma2019ADS, title={A dissipatively stabilized Mott insulator of photons}, author={Ruichao Ma and Brendan Saxberg and Clai Owens and Nelson Leung and Yao Lu and Jonathan Simon and David I. Schuster}, journal={Nature}, year={2019}, volume={566}, pages={51-57} }

Superconducting circuits are a competitive platform for quantum computation because they offer controllability, long coherence times and strong interactions—properties that are essential for the study of quantum materials comprising microwave photons. However, intrinsic photon losses in these circuits hinder the realization of quantum many-body phases. Here we use superconducting circuits to explore strongly correlated quantum matter by building a Bose–Hubbard lattice for photons in the…
