Doping evolution of spin excitations in LaSrNiO/SrLaAlO superconducting thin films
Hengyang Zhong, Bo Hao, Anni Chen +11
Ambient-pressure superconductivity in compressively strained bilayer nickelate films provides a unique platform to test pairing scenarios, yet the evolution of magnetism with carri…
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…
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…
Quantum confinement effect in Sb thin films
Anuradha Wijesinghe, Yongxi Ou, Anjali Rathore +7
Antimony (Sb), an element with strong spin-orbit coupling, is predicted to undergo a topological phase transition from a topological semimetal to a topological insulator as its dim…
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…
