Detuning Axis Pulsed Spectroscopy of Valley-Orbital States in Si/SiGe Quantum Dots
Edward H. Chen, Kate Raach, Andrew Pan +16
Silicon quantum dot qubits must contend with low-lying valley excited states which are sensitive functions of the quantum well heterostructure and disorder; quantifying and maximiz…
Resonant Exchange Operation in Triple-Quantum-Dot Qubits for Spin-Photon Transduction
Andrew Pan, Tyler E. Keating, Mark F. Gyure +5
Triple quantum dots (TQDs) are promising semiconductor spin qubits because of their all-electrical control via fast, tunable exchange interactions and immunity to global magnetic f…
Spin-Blockade Spectroscopy of Si/SiGe Quantum Dots
A. M. Jones, E. J. Pritchett, E. H. Chen +15
We implement a technique for measuring the singlet-triplet energy splitting responsible for spin-to-charge conversion in semiconductor quantum dots. This method, which requires fas…
Negativity of the Coarse Grained Wigner Function as a Measure of Quantal Behavior
Tyler E Keating, Adam T. C. Steege, Arjendu K. Pattanayak
The negativity of a given state's Wigner function has been proposed as a measure of quantumness of that state in a unipartite system. This otherwise physically intuitive and useful…
