Hybrid Circuit Cavity (IMAGE) Aalto University Caption This shows a merger of three quantum systems: a superconducting quantum qubit, or, qubit (spheres) interacting with two different resonant cavities. A low frequency phonon cavity (vibrating string) was used as storage of quantum information from the qubit, whereas an electrical microwave cavity (represented by the mirrors) acted as a means of communicating to the outside world. The idea could be used as a building block in the emerging field of quantum information and communication.
