Depth-Resolved Lattice Distortions in a Silicon-Germanium Qubit Host
Jonathan C. Marcks, E. S. Joseph, J. Reily +6
Semiconductor qubits, promising for quantum computation, inherit properties from their host lattice. Quantum dot spins, occupying the local lowest energy states in the conduction b…
Complete measurement of tunnel- and valley-coupling parameters in a silicon double quantum dot
Daniel J. King, Minyoung Kim, J. Reily +4
Tunneling is essential in the initialization, measurement, and control of quantum dot qubits. In silicon, such tunneling connects not only the qubit states but also valley minima i…
High-fidelity EDSR in Si/SiGe Wiggle Wells
Hudaiba Soomro, Minyoung Kim, Avani Vivrekar +3
Si/SiGe quantum wells that incorporate Ge concentration oscillations, known as long-period Wiggle Wells, have been shown to enhance the Dresselhaus spin-orbit coupling of conductio…
Individually tunable Si/SiGe quantum dot operating voltages via gate-biased illumination
Jared Benson, Sanghyeok Park, Owen M. Eskandari +6
Semiconductor quantum dot qubits often require very different voltages on each gate to bring them to a correct operating point. Here, we present a method by which one can controlla…
Using a spin-triplet encoding to enhance shuttling fidelities in Si/SiGe quantum wells
Merritt P. R. Losert, S. N. Coppersmith, Mark Friesen
Spatial variations of the valley splitting in a quantum well present a key challenge for conveyor-mode shuttling of electron spins in Si/SiGe, giving rise to Landau-Zener-like exci…
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…
