Operating two exchange-only qubits in parallel
Mateusz T. Mądzik, Florian Luthi, Gian Giacomo Guerreschi +38
Semiconductors are among the most promising platforms to implement large-scale quantum computers, as advanced manufacturing techniques allow fabrication of large quantum dot arrays…
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…
Control of threshold voltages in Si/SiGe quantum devices via optical illumination
M. A. Wolfe, Brighton X. Coe, Justin S. Edwards +9
Optical illumination of quantum-dot qubit devices at cryogenic temperatures, while not well studied, is often used to recover operating conditions after undesired shocking events o…
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…
SiGe quantum wells with oscillating Ge concentrations for quantum dot qubits
Thomas McJunkin, Benjamin Harpt, Yi Feng +10
Large-scale arrays of quantum-dot spin qubits in Si/SiGe quantum wells require large or tunable energy splittings of the valley states associated with degenerate conduction band mi…
Toward Robust Autotuning of Noisy Quantum Dot Devices
Joshua Ziegler, Thomas McJunkin, E. S. Joseph +7
The current autotuning approaches for quantum dot (QD) devices, while showing some success, lack an assessment of data reliability. This leads to unexpected failures when noisy or…
