Quantum computing and condensed matter physics with microwave photons

Circuit Quantum Electrodynamics

Microwave photons in a superconducting transmission line cavity are strongly coupled to a qubit, or "artificial atom," in direct analogy with optical cavity QED.  This a key component of everything we do, including superconducting quantum computing, hybrid quantum inofrmation, and quantum simulation.
