Quasiparticle relaxation of superconducting qubits in the presence of flux
G. Catelani, Jens Koch, L. Frunzio +3
Quasiparticle tunneling across a Josephson junction sets a limit for the lifetime of a superconducting qubit state. We develop a general theory of the corresponding decay rate in a…
Coherent oscillations between classically separable quantum states of a superconducting loop
Vladimir E. Manucharyan, Jens Koch, Markus Brink +2
Ten years ago, coherent oscillations between two quantum states of a superconducting circuit differing by the presence or absence of a single Cooper pair on a metallic island were…
Proposal for generating and detecting multi-qubit GHZ states in circuit QED
Lev S. Bishop, L. Tornberg, D. Price +8
We propose methods for the preparation and entanglement detection of multi-qubit GHZ states in circuit quantum electrodynamics. Using quantum trajectory simulations appropriate for…
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…
