InAs-Al Hybrid Devices Passing the Topological Gap Protocol
Morteza Aghaee, Arun Akkala, Zulfi Alam +124
We present measurements and simulations of semiconductor-superconductor heterostructure devices that are consistent with the observation of topological superconductivity and Majora…
Spin-Relaxation Mechanisms in InAs Quantum Well Heterostructures
J. D. S. Witt, S. J. Pauka, G. C. Gardner +6
The spin-orbit interaction and spin-relaxation mechanisms of a shallow InAs quantum well heterostructure are investigated by magnetoconductance measurements as a function of an app…
Dispersive readout of Majorana qubits
Thomas B. Smith, Maja C. Cassidy, David J. Reilly +2
We analyze a readout scheme for Majorana qubits based on dispersive coupling to a resonator. We consider two variants of Majorana qubits: the Majorana transmon and the Majorana box…
Transparent Gatable Superconducting Shadow Junctions
Sabbir A. Khan, Charalampos Lampadaris, Ajuan Cui +14
Gate tunable junctions are key elements in quantum devices based on hybrid semiconductor-superconductor materials. They serve multiple purposes ranging from tunnel spectroscopy pro…
Autonomous tuning and charge state detection of gate defined quantum dots
J. Darulová, S. J. Pauka, N. Wiebe +5
Defining quantum dots in semiconductor based heterostructures is an essential step in initializing solid-state qubits. With growing device complexity and increasing number of funct…
Repairing the Surface of InAs-based Topological Heterostructures
S. J. Pauka, J. D. S. Witt, C. N. Allen +9
Candidate systems for topologically-protected qubits include two-dimensional electron gases (2DEGs) based on heterostructures exhibiting a strong spin-orbit interaction (SOI) and s…
