Demonstration of Two-Qubit Algorithms with a Superconducting Quantum Processor
L. DiCarlo, J. M. Chow, J. M. Gambetta +8
By harnessing the superposition and entanglement of physical states, quantum computers could outperform their classical counterparts in solving problems of technological impact, su…
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…
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…
