Process verification of two-qubit quantum gates by randomized benchmarking
A. D. Córcoles, Jay M. Gambetta, Jerry M. Chow +5
We implement a complete randomized benchmarking protocol on a system of two superconducting qubits. The protocol consists of randomizing over gates in the Clifford group, which exp…
Entanglement of two superconducting qubits in a waveguide cavity via monochromatic two-photon excitation
S. Poletto, Jay M. Gambetta, Seth T. Merkel +9
We report a system where fixed interactions between non-computational levels make bright the otherwise forbidden two-photon 00 --> 11 transition. The system is formed by hand selec…
Characterization of addressability by simultaneous randomized benchmarking
Jay M. Gambetta, A. D. Corcoles, S. T. Merkel +9
The control and handling of errors arising from cross-talk and unwanted interactions in multi-qubit systems is an important issue in quantum information processing architectures. W…
Efficient measurement of quantum gate error by interleaved randomized benchmarking
Easwar Magesan, Jay M. Gambetta, B. R. Johnson +9
We describe a scalable experimental protocol for obtaining estimates of the error rate of individual quantum computational gates. This protocol, in which random Clifford gates are…
Superconducting qubit in waveguide cavity with coherence time approaching 0.1ms
Chad Rigetti, Stefano Poletto, Jay M. Gambetta +10
We report a superconducting artificial atom with an observed quantum coherence time of T2*=95us and energy relaxation time T1=70us. The system consists of a single Josephson juncti…
Complete universal quantum gate set approaching fault-tolerant thresholds with superconducting qubits
Jerry M. Chow, Jay M. Gambetta, A. D. Corcoles +9
We use quantum process tomography to characterize a full universal set of all-microwave gates on two superconducting single-frequency single-junction transmon qubits. All extracted…
