UNSW researchers report a two-qubit logic gate in silicon

Nov 21, 2014

Menno Veldhorst and colleagues report controlled-NOT operations between electron spins in silicon quantum dots. The preprint appeared in November 2014; the expanded experiment was published in Nature in October 2015.

Why it matters

Coupling silicon spin qubits for logic operations connects earlier single-qubit demonstrations to the building blocks needed for a quantum processor.
