Low-frequency spin qubit energy splitting noise in highly purified 28Si/SiGe

T Struck, A Hollmann, F Schauer, O Fedorets… - npj Quantum …, 2020 - nature.com
We identify the dominant source for low-frequency spin qubit splitting noise in a highly
isotopically-purified silicon device with an embedded nanomagnet and a spin echo decay …

Molecular formations and spectra due to electron correlations in three-electron hybrid double-well qubits

C Yannouleas, U Landman - Physical Review B, 2022 - APS
We show that systematic full configuration-interaction (FCI) calculations enable prediction of
the energy spectra and the intrinsic spatial and spin structures of the many-body wave …

Quantum Processors in Silicon

DK Ferry - Quantum Information in the Nanoelectronic World, 2024 - Springer
The first idea for a qubit based upon Si arises from the suggestion of Kane to use a 31P
dopant in isotopically pure 28Si (silicon, like many materials, has different isotopes that have …
