WHY INCLUDED

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 Computing

Simmons 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.

Defining contributions

Work, in context
  1. 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.

  2. 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.

    Founding Silicon Quantum Computing

    Simmons founded Silicon Quantum Computing to develop processors based on precisely positioned atoms in silicon, extending the fabrication and device work into a dedicated quantum-computing company.

    Founder, according to Silicon Quantum Computing’s company history.

Keep in perspective

The institutional biography does not date the individual device milestones; these remain undated. This is Michelle Simmons of SQC, a different person from Photonic co-founder Stephanie Simmons.
