Epitaxial NbN-junction-based self-shunted superconducting flux qubit with high anharmonicity
Tokunoshin Uchida, Shingo Nozaki, Daiki Kurihara +5
We report a demonstration of a self-shunted superconducting flux qubit (SSFQ) as an ultracompact, strongly anharmonic, and long-lifetime qubit by using the full epitaxially grown N…
Sidewall spacer passivated epitaxial NbN/AlN/NbN Josephson junctions for superconducting qubit applications
Koki Honda, Daiki Kurihara, Hiroki Kutsuma +2
Epitaxial NbN/AlN/NbN Josephson junctions are promising alternatives to conventional Al/AlO/Al junctions for superconducting qubits due to their crystalline tunnel barriers and…
Wide-field magnetic imaging of shielding-current-driven vortex rearrangement under local heating using diamond quantum sensors
Ryoei Ota, Shunsuke Nishimura, Koki Honda +6
Understanding and controlling vortex motion in superconductors are important both for suppressing dissipation in superconducting devices and for device applications that exploit vo…
Ultralow-power coherent qubit control using AQFP logic at millikelvin temperatures
Hiroto Mukai, Akiyoshi Tomonaga, Rui Wang +5
Qubit controllers are essential for scaling superconducting quantum processors, but implementing them at the 10 mK stage of a dilution refrigerator remains challenging due to strin…
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…
