Kerr nonlinearity and parametric amplification with an Al-InAs superconductor-semiconductor Josephson junction
Z. Hao, T. Shaw, M. Hatefipour +5
Nearly quantum limited Josephson parametric amplifiers (JPAs) are essential components in superconducting quantum circuits. However, higher order nonlinearities of the Josephson co…

Andreev reflection of quantum Hall states through a quantum point contact
Mehdi Hatefipour, Joseph J. Cuozzo, Ido Levy +4
We investigate the interplay between the quantum Hall (QH) effect and superconductivity in InAs surface quantum well (SQW)/NbTiN heterostructures using a quantum point contact (QPC…

Quasiparticle dynamics in epitaxial Al-InAs planar Josephson junctions
Bassel Heiba Elfeky, William M. Strickland, Jaewoo Lee +7
Quasiparticle (QP) effects play a significant role in the coherence and fidelity of superconducting quantum circuits. The Andreev bound states of high transparency Josephson juncti…
