Quantum information in silicon
Spin-qubit proposals, single-atom control and two-qubit logic. Four sourced contributions to read in sequence.
- STOP 1 OF 4 · Propose a spin qubit
Daniel Loss
1998 · Electron spins as quantum-dot qubits
With David DiVincenzo, Loss proposed a universal quantum-computing architecture using the spins of single electrons in coupled quantum dots. The gates rely on local spin operations and controlled interactions between neighboring dots. The original paper also analyzes gate quality in the presence of environmental decoherence.
Joint theoretical proposal by Daniel Loss and David P. DiVincenzo.

Andrea Morello
2012 · A single-atom electron qubit
Coauthored the demonstration of an electron-spin qubit associated with a single phosphorus atom in silicon, as documented in UNSW’s research record.
Coauthor of the single-atom electron-spin experiment, as documented by UNSW; shared experimental credit.
Read the contribution in context - STOP 3 OF 4 · Perform two-qubit logic
Andrew S. Dzurak
2015 · Two-qubit logic in silicon
Dzurak coauthored the demonstration of a controlled two-qubit logic gate using individual electron spins in silicon quantum dots. The experiment used an exchange interaction to connect spin qubits and was published in Nature in 2015.
Coauthor of the silicon two-qubit experiment; the demonstration is credited to the full research team.

Michelle Y. Simmons
· 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.
