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…
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…
Protecting superconducting qubits from external sources of loss and heat
Antonio D. Córcoles, Jerry M. Chow, Jay M. Gambetta +6
We characterize a superconducting qubit before and after embedding it along with its package in an absorptive medium. We observe a drastic improvement in the effective qubit temper…
A simple all-microwave entangling gate for fixed-frequency superconducting qubits
Jerry M. Chow, A. D. Corcoles, Jay M. Gambetta +8
We demonstrate an all-microwave two-qubit gate on superconducting qubits which are fixed in frequency at optimal bias points. The gate requires no additional subcircuitry and is tu…
