Life after charge noise: recent results with transmon qubits
A. A. Houck, Jens Koch, M. H. Devoret +2
We review the main theoretical and experimental results for the transmon, a superconducting charge qubit derived from the Cooper pair box. The increased ratio of the Josephson to c…
Randomized benchmarking and process tomography for gate errors in a solid-state qubit
J. M. Chow, J. M. Gambetta, L. Tornberg +7
We present measurements of single-qubit gate errors for a superconducting qubit. Results from quantum process tomography and randomized benchmarking are compared with gate errors o…
Nonlinear response of the vacuum Rabi resonance
Lev S. Bishop, J. M. Chow, Jens Koch +5
On the level of single atoms and photons, the coupling between atoms and the electromagnetic field is typically very weak. By employing a cavity to confine the field, the strength…
Controlling the spontaneous emission of a superconducting transmon qubit
A. A. Houck, J. A. Schreier, B. R. Johnson +8
We present a detailed characterization of coherence in seven transmon qubits in a circuit QED architecture. We find that spontaneous emission rates are strongly influenced by far o…
Discontinuous current-phase relations in small 1D Josephson junction arrays
Jens Koch, Karyn Le Hur
We study the Josephson effect in small one-dimensional (1D) Josephson junction arrays. For weak Josephson tunneling, topologically different regions in the charge-stability diagram…
