Building strongly interacting photonic materials

A collaboration of the Simon and Schuster groups at the University of Chicago MRSEC  have realized a photonic strongly interacting Mott insulator using a 1D lattice of superconducting qubits (see figure).   A key difference between photonic and electronicmaterials is that photon number is not conserved.  We have developed dissipative stabilization protocols which can stabilize incompressible phases, including the Mott insulator.
