Develops quantum devices by placing atoms precisely in silicon, connecting single-atom electronics and coupled-qubit control to the manufacturing of silicon quantum processors.
UNSW SydneySilicon Quantum ComputingSimmons pursues a route to quantum computing in which the placement of individual atoms is part of the device design. Her research record connects atomic-scale fabrication to electronic components and operations on silicon qubits. She also founded Silicon Quantum Computing to develop that approach commercially. Her inclusion rests on the connection between a distinctive manufacturing method and demonstrated device physics, with academic research and company development clearly identified as related but different activities.

Work, in context- Year not documented
Single-atom electronic devices
Simmons’s research group developed a single-atom transistor and other electronic structures fabricated with atomic precision. These results show how individual dopant atoms can become deliberately engineered components in silicon devices.
Research-group leader credited by UNSW for the collaborative single-atom device work.
Source-supported recordUNSW Sydney - Year not documented
Coupled atom-based silicon qubits
Her UNSW research record includes two-qubit gate work in an atom-based silicon system. This connects precision fabrication to the controlled interactions needed to process information across more than one qubit.
Research-group leader credited by UNSW for collaborative atom-based two-qubit work.
