Welcome to the Koch Research Group

Quantum physics has long had the reputation of being a theory describing the smallest of things: atoms, electrons, and other subatomic particles. Modern efforts in quantum engineering have shown that much larger, engineered structures such as superconducting circuits can show quantum effects very similar to those known for atoms.

Fluxonium-thumbnailIn our theory research, we explore the potential of superconducting circuits for quantum computation, and quantum simulation.  In particular, we study interacting photons in circuit QED arrays, their nonequilibrium steady-states, dissipative phase transitions, open-system quantum simulation, and help devise new ways for enhancing quantum coherence in superconducting qubits.
