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…
Omnidirectional shuttling to avoid valley excitations in Si/SiGe quantum wells
Róbert Németh, Vatsal K. Bandaru, Pedro Alves +7
Conveyor-mode shuttling is a key approach for implementing intermediate-range coupling between electron-spin qubits in quantum dots. Initial implementations are encouraging; howeve…
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…
