Few-electron Single and Double Quantum Dots in an InAs Two-Dimensional Electron Gas
Christopher Mittag, Jonne V. Koski, Matija Karalic +8
Most proof-of-principle experiments for spin qubits have been performed using GaAs-based quantum dots because of the excellent control they offer over tunneling barriers and the or…
Gate-defined Quantum Point Contact in an InSb Two-dimensional Electron Gas
Zijin Lei, Christian A. Lehner, Erik Cheah +5
We investigate an electrostatically defined quantum point contact in a high-mobility InSb two-dimensional electron gas. Well-defined conductance plateaus are observed, and the subb…
Accurate characterization of tip-induced potential using electron interferometry
A. Iordanescu, S. Toussaint, G. Bachelier +5
Using the tip of a scanning probe microscope as a local electrostatic gate gives access to real space information on electrostatics as well as charge transport at the nanoscale, pr…
Anodic Oxidation of Epitaxial Superconductor-Semiconductor Hybrids
Asbjørn C. C. Drachmann, Rosa E. Diaz, Candice Thomas +10
We demonstrate a new fabrication process for hybrid semiconductor-superconductor heterostructures based on anodic oxidation (AO), allowing controlled thinning of epitaxial Al films…
Disorder broadening of even denominator fractional quantum Hall states in the presence of a short-range alloy potential
E. Kleinbaum, Hongxi Li, N. Deng +3
We study energy gaps of the and fractional quantum Hall states in a series of two-dimensional electron gases containing alloy disorder. We found that gaps at these…
Long-Distance Superexchange between Semiconductor Quantum-Dot Electron Spins
Haifeng Qiao, Yadav P. Kandel, Saeed Fallahi +4
Because of their long coherence times and potential for scalability, semiconductor quantum-dot spin qubits hold great promise for quantum information processing. However, maintaini…
