Photonic Materials in Quantum Circuits

Superconducting quantum circuits are an emerging quantum computing platform which now competes aggressively with the best trapped-ion systems. In a collaboration with the Schuster Lab, we are using the exquisite quantum coherence of these devices to build synthetic materials composed of strongly interacting microwave photons.


  • The figure above shows our first attempt at an autonomously stabilized photonic Mott insulator
  • We have demonstrated the first topologically insulating circuit, in both the time-reversal-symmetric and time-reversal-broken regimes.
  • We have developed theoretical descriptions of topologically non-trivial, interacting Harper-Hofstadter models, as well as tools for populating them with particles at zero-temperature and non-zero chemical potential.
  • The macroscopic nature of these systems enables us to achieve single-photon, single-lattice site resolution-- akin to a quantum gas microscope for photonic quantum materials!
