Phonon spectral density in a GaAs/AlGaAs double quantum dot
Andrea Hofmann, Christian Karlewski, Andreas Heimes +6
We study phonon emission in a GaAs/AlGaAs double quantum dot by monitoring the tunneling of a single electron between the two dots. We prepare the system such that a known amount o…
Automated tuning of double quantum dots into specific charge states using neural networks
Renato Durrer, Benedikt Kratochwil, Jonne V. Koski +5
While quantum dots are at the forefront of quantum device technology, tuning multi-dot systems requires a lengthy experimental process as multiple parameters need to be accurately…
Quantum dot thermometry at ultra-low temperature in a dilution refrigerator with a He immersion cell
Giorgio Nicolí, Peter Märki, Beat A. Bräm +7
Experiments performed at a temperature of a few millikelvin require effective thermalization schemes, low-pass filtering of the measurement lines and low-noise electronics. Here, w…
Strong photon coupling to the quadrupole moment of an electron in solid state
Jonne V. Koski, Andreas J. Landig, Maximilian Russ +11
The implementation of circuit quantum electrodynamics allows coupling distant qubits by microwave photons hosted in on-chip superconducting resonators. Typically, the qubit-photon…
Achieving Balance of Valley Occupancy in Narrow AlAs Quantum Wells
A. R. Khisameeva, A. V. Shchepetilnikov, V. M. Muravev +7
Terahertz photoconductivity of m and m Hall bars fabricated from narrow AlAs quantum wells (QWs) of different widths is investigated in this paper. The photoresponse i…
Nagaoka ferromagnetism observed in a quantum dot plaquette
Juan P. Dehollain, Uditendu Mukhopadhyay, Vincent P. Michal +7
Engineered, highly-controllable quantum systems hold promise as simulators of emergent physics beyond the capabilities of classical computers. An important problem in many-body phy…
Coherent long-distance spin-qubit-transmon coupling
A. J. Landig, J. V. Koski, P. Scarlino +10
Spin qubits and superconducting qubits are among the promising candidates for a solid state quantum computer. For the implementation of a hybrid architecture which can profit from…
Auger-spectroscopy in quantum Hall edge channels: a possible resolution to the missing energy problem
T. Krähenmann, S. G. Fischer, M. Röösli +6
Quantum Hall edge channels offer an efficient and controllable platform to study quantum transport in one dimension. Such channels are a prospective tool for the efficient transfer…
Loading a quantum-dot based "Qubyte" register
C. Volk, A. M. J. Zwerver, U. Mukhopadhyay +8
Electrostatically defined quantum dot arrays offer a compelling platform for quantum computation and simulation. However, tuning up such arrays with existing techniques becomes imp…
