High-Fidelity Hole Spin Qubits Reveal Quadrupolar Nuclear-Bath Dynamics in Isotopically Purified Planar Germanium
Jian Zeng, Xiangjun Tan, Hongzhang Wang +10
Planar Germanium has emerged as a promising platform to build spin-based large scale quantum computers. By exploiting the anisotropic hyperfine interaction of holes in Ge, qubits w…
Tunable Wigner Molecules in a Germanium Quantum Dot
Chenggang Yang, Jun Lu, Hongzhang Wang +7
The interplay between Coulomb interactions and kinetic energy underlies many exotic phases in condensed matter physics. In a two-dimensional electronic system, If Coulomb interacti…
A coherent nanomechanical oscillator driven by single-electron tunnelling
Yutian Wen, N. Ares, F. J. Schupp +3
A single-electron transistor incorporated as part of a nanomechanical resonator represents an extreme limit of electron-phonon coupling. While it allows for fast and sensitive elec…
Measuring carbon nanotube vibrations using a single-electron transistor as a fast linear amplifier
Yutian Wen, N. Ares, T. Pei +2
We demonstrate sensitive and fast electrical measurements of a carbon nanotube mechanical resonator. The nanotube is configured as a single-electron transistor, whose conductance i…
Hyperfine and spin-orbit coupling effects on decay of spin-valley states in a carbon nanotube
T. Pei, A. Pályi, M. Mergenthaler +5
The decay of spin-valley states is studied in a suspended carbon nanotube double quantum dot via leakage current in Pauli blockade and via dephasing and decoherence of a qubit. Fro…
Resonant optomechanics with a vibrating carbon nanotube and a radio-frequency cavity
Natalia Ares, Tian Pei, Aquila Mavalankar +4
In an optomechanical setup, the coupling between cavity and resonator can be increased by tuning them to the same frequency. We study this interaction between a carbon nanotube res…
