Large quantum dot energy level shifts in anomalous photon-assisted tunneling
Jared Benson, C. E. Sturner, A. R. Huffman +12
Orbital energy splittings are important quantum dot parameters for the operation of hole spin qubits. They are known to depend on the lateral confinement of the quantum dots. Howev…
Direct measurement of the energy spectrum of a quantum dot qubit
J. Reily, Daniel J. King, Jonathan C. Marcks +8
The mapping between gate voltages applied to a double quantum dot, and the parameters of a Hubbard-like Hamiltonian, is of utmost importance for understanding and operating spin qu…
FAlCon: A unified framework for algorithmic control of quantum dot devices
Tyler J. Kovach, Daniel Schug, Zach D. Merino +3
As spin-based quantum systems scale, their setup and control complexity increase sharply. In semiconductor quantum dot (QD) experiments, device-to-device variability, heterogeneous…
Bootstrapping, autonomous testing, and initialization system for Si/SiGe multi-quantum-dot devices
Tyler J. Kovach, Daniel Schug, M. A. Wolfe +7
Semiconductor quantum dot (QD) devices have become central to advancements in spin-based quantum computing. However, the increasing complexity of modern QD devices makes calibratio…
Fast high-fidelity baseband reset of a latched state for quantum dot qubit readout
Piotr Marciniec, M. A. Wolfe, Tyler Kovach +9
A common method for reading out the state of a spin qubit is by latching one logical qubit state, either or , onto a different, metastable charge state. Such…
Automation of Quantum Dot Measurement Analysis via Explainable Machine Learning
Daniel Schug, Tyler J. Kovach, M. A. Wolfe +6
The rapid development of quantum dot (QD) devices for quantum computing has necessitated more efficient and automated methods for device characterization and tuning. This work demo…
