Superconducting flux qubit with ferromagnetic Josephson -junction operating at zero magnetic field
Sunmi Kim, Leonid V. Abdurakhimov, Duong Pham +6
Conventional superconducting flux qubits require the application of a precisely tuned magnetic field to set the operation point at half a flux quantum through the qubit loop, which…

Controlling qubit-oscillator systems using linear parameter sweeps
Sahel Ashhab, Tomoko Fuse, Fumiki Yoshihara +2
We investigate the dynamics of a qubit-oscillator system under the influence of a linear sweep of system parameters. We consider two main cases. In the first case, we consider swee…

Enhanced coherence of all-nitride superconducting qubits epitaxially grown on silicon substrate
Sunmi Kim, Hirotaka Terai, Taro Yamashita +6
Improving the coherence of superconducting qubits is a fundamental step towards the realization of fault-tolerant quantum computation. However, coherence times of quantum circuits…
