Superconducting flux qubit with ferromagnetic Josephson $\pi$-junction operating at zero magnetic field

Autor: Kim, Sunmi, Abdurakhimov, Leonid V., Pham, Duong, Qiu, Wei, Terai, Hirotaka, Ashhab, Sahel, Saito, Shiro, Yamashita, Taro, Semba, Kouichi

Publikováno v: Commun Mater 5, 216 (2024)

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 complicates the on-chip integration of this type of device. It has be
