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…
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…
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…
