TWO-DIMENSIONAL CONVEYOR-MODE SPIN QUBIT SHUTTLING DEVICES
WARF: P250006US01
Inventors: Mark Eriksson, Mark Friesen, Merritt Losert, Vatsal Bandaru
A need exists for a quantum computing system that increases qubit coupling capabilities and reduces spin decoherence due to valley splitting without exacerbating the fan-out problem.
The Invention
UW-Madison researchers have developed an electron shuttling scheme for silicon quantum dot qubits that allows for two-dimensional transport of the qubit over large distances. This advancement allows the qubit to avoid dangerous regions of the device during shuttling. The technique involves using a 2D pattern of gates, rather than a quasi-1D pattern, which provides plenty of transverse motion, as desired.
