Strategies for enhancing spin-shuttling fidelities in Si/SiGe quantum wells with random-alloy disorder
Merritt P. Losert, Max Oberländer, Julian D. Teske +5
Coherent coupling between distant qubits is needed for any scalable quantum computing scheme. In quantum dot systems, one proposal for long-distance coupling is to coherently trans…
Multielectron dots provide faster Rabi oscillations when the core electrons are strongly confined
H. Ekmel Ercan, Christopher R. Anderson, S. N. Coppersmith +2
Increasing the number of electrons in electrostatically confined quantum dots can enable faster qubit gates. Although this has been experimentally demonstrated, a detailed quantita…
Practical Strategies for Enhancing the Valley Splitting in Si/SiGe Quantum Wells
Merritt P. Losert, M. A. Eriksson, Robert Joynt +4
Silicon/silicon-germanium heterostructures have many important advantages for hosting spin qubits. However, controlling the valley splitting (the energy splitting between the two l…
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…
Spin-orbit enhancement in Si/SiGe heterostructures with oscillating Ge concentration
Benjamin D. Woods, M. A. Eriksson, Robert Joynt +1
We show that Ge concentration oscillations within the quantum well region of a Si/SiGe heterostructure can significantly enhance the spin-orbit coupling of the low-energy conductio…
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…
