Query: Circuit Quantum Electrodynamics with a Superconducting Quantum Point
  Contact   We consider a superconducting quantum point contact in a circuit quantum
electrodynamics setup. We study three different configurations, attainable with
current technology, where a quantum point contact is coupled galvanically to a
coplanar waveguide resonator. Furthermore, we demonstrate that the strong and
ultrastrong coupling regimes can be achieved with realistic parameters,
allowing the coherent exchange between a superconducting quantum point contact
and a quantized intracavity field.
