A silicon-quantum-computing researcher and company founder whose work connects two-qubit logic in silicon with efforts to develop processors using semiconductor manufacturing approaches.
DiraqarXiv / NatureDzurak’s contribution centers on making silicon a controllable quantum-computing medium and pursuing its commercial development. He coauthored an experimental two-qubit gate using electron spins in silicon quantum dots, an important step beyond isolated single-qubit operation. As Diraq’s founder and chief executive, he also directs a company pursuing silicon-based processors. The significance lies in this connection between a demonstrated building block and an engineering program; large-scale performance remains something to demonstrate.

Work, in context- 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.
