Resolving photon number states in a superconducting circuit
Article Abstract:
A circuit quantum electrodynamics (QED) experiment is described in the strong dispersive limit, which is a new regime where a single photon has a large effect on a superconducting quantum bit (qubit) without ever being absorbed. The results have shown that no photons are absorbed by this process and hence non-classical states of light can be generated by measuring and performing qubit-photon conditional logic, which is the basis of a logic bus for a quantum computer.

Coupling superconducting qubits via a cavity bus
Article Abstract:
A quantum bus is used to couple two superconducting qubits on opposite sides of a chip by using microwave photons confined in a transmission line cavity. Fast control of the qubits is used for showing coherent transfer of quantum states between the qubits and the cavity is used to perform multiplexed control and measurement of the qubit states.
