Tunable anharmonicity in Sn-InAs nanowire transmons beyond the short junction limit
Amrita Purkayastha, Amritesh Sharma, Param J. Patel +11
The anharmonicity of a transmon qubit, defined as the difference in energy level spacing, is a key design parameter. In transmons built from hybrid superconductor-semiconductor Jos…
Cryogenic growth of aluminum: structural morphology, optical properties, superconductivity and microwave dielectric loss
Wilson J. Yánez-Parreño, Teun A. J. van Schijndel, Anthony P. McFadden +7
We explore the molecular beam epitaxy synthesis of superconducting aluminum thin films grown on c-plane sapphire substrates at cryogenic temperatures of 6 K and compare their behav…
Transmon qubit using Sn as a junction superconductor
Amrita Purkayastha, Amritesh Sharma, Param J. Patel +11
Superconductor qubits typically use aluminum-aluminum oxide tunnel junctions to provide the non-linear inductance. Junctions with semiconductor barriers make it possible to vary th…
Sn-InAs nanowire shadow-defined Josephson junctions
Amritesh Sharma, An-Hsi Chen, Connor P. Dempsey +6
Interest in hybrid electronic devices for quantum science is driving the research into superconductor-semiconductor materials combinations. Here we study InAs nanowires coated with…
Planar Josephson Junctions Templated by Nanowire Shadowing
P. Zhang, A. Zarassi, M. Pendharkar +16
More and more materials, with a growing variety of properties, are built into electronic devices. This is motivated both by increased device performance and by the studies of mater…
Hysteretic magnetoresistance in nanowire devices due to stray fields induced by micromagnets
Y. Jiang, E. J. de Jong, V. van de Sande +4
We study hysteretic magnetoresistance in InSb nanowires due to stray magnetic fields from CoFe micromagnets. Devices without any ferromagnetic components show that the magnetoresis…
