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…
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…
Performance of high impedance resonators in dirty dielectric environments
Jann H. Ungerer, Deepankar Sarmah, Artem Kononov +4
High-impedance resonators are a promising contender for realizing long-distance entangling gates between spin qubits. Often, the fabrication of spin qubits relies on the use of gat…
Phase-dependent microwave response of a graphene Josephson junction
Roy Haller, Gergő Fülöp, David Indolese +10
Gate-tunable Josephson junctions embedded in a microwave environment provide a promising platform to in-situ engineer and optimize novel superconducting quantum circuits. The key q…
Compact SQUID realized in a double layer graphene heterostructure
David I. Indolese, Paritosh Karnatak, Artem Kononov +7
Two-dimensional systems that host one-dimensional helical states are exciting from the perspective of scalable topological quantum computation when coupled with a superconductor. G…
Blocking-state influence on shot noise and conductance in quantum dots
M. -C. Harabula, V. Ranjan, R. Haller +2
Quantum dots (QDs) investigated through electron transport measurements often exhibit varying, state-dependent tunnel couplings to the leads. Under specific conditions, weakly coup…
