Coherent control of a few-channel hole type gatemon qubit
Han Zheng, Luk Yi Cheung, Nikunj Sangwan +9
Gatemon qubits are the electrically tunable cousins of superconducting transmon qubits. In this work, we demonstrate the full coherent control of a gatemon qubit based on hole carr…
Photon-mediated long range coupling of two Andreev level qubits
L. Y. Cheung, R. Haller, A. Kononov +9
In a superconducting weak link, the supercurrent is carried by Andreev bound states (ABSs) formed by the phase-coherent reflection of electrons and their time-reversed partners. A…
Charge-4e supercurrent in a two-dimensional InAs-Al superconductor-semiconductor heterostructure
Carlo Ciaccia, Roy Haller, Asbjørn C. C. Drachmann +4
Superconducting qubits with intrinsic noise protection offer a promising approach to improve the coherence of quantum information. Crucial to such protected qubits is the encoding…
Gate Tunable Josephson Diode in Proximitized InAs Supercurrent Interferometers
Carlo Ciaccia, Roy Haller, Asbjørn C. C. Drachmann +4
The Josephson diode (JD) is a non-reciprocal circuit element that supports a larger critical current in one direction compared to the other. This effect has gained a growing intere…
