Single-shot latched readout of a quantum dot qubit using barrier gate pulsing
Sanghyeok Park, Jared Benson, J. Corrigan +4
Latching techniques are widely used to enhance readout of qubits. These methods require precise tuning of multiple tunnel rates, which can be challenging to achieve under realistic…
Ultra-dispersive resonator readout of a quantum-dot qubit using longitudinal coupling
Benjamin Harpt, J. Corrigan, Nathan Holman +10
We perform readout of a quantum-dot hybrid qubit coupled to a superconducting resonator through a parametric, longitudinal interaction mechanism. Our experiments are performed with…
Longitudinal coupling between a Si/SiGe quantum dot and an off-chip TiN resonator
J. Corrigan, Benjamin Harpt, Nathan Holman +10
Superconducting cavities have emerged as a key tool for measuring the spin states of quantum dots. So far however, few experiments have explored longitudinal couplings between dots…
Latched readout for the quantum dot hybrid qubit
J. Corrigan, J. P. Dodson, Brandur Thorgrimsson +5
A primary method of reading out a quantum dot hybrid qubit involves projection of the logical basis onto distinct charge states that are readily detected by an integrated charge se…
Valley splittings in Si/SiGe quantum dots with a germanium spike in the silicon well
Thomas McJunkin, E. R. MacQuarrie, Leah Tom +11
Silicon-germanium heterostructures have successfully hosted quantum dot qubits, but the intrinsic near-degeneracy of the two lowest valley states poses an obstacle to high fidelity…
How valley-orbit states in silicon quantum dots probe quantum well interfaces
J. P. Dodson, H. Ekmel Ercan, J. Corrigan +7
The energies of valley-orbit states in silicon quantum dots are determined by an as yet poorly understood interplay between interface roughness, orbital confinement, and electron i…
