Researchers demonstrate a two-qubit gate in diamond

Feb 12, 2004

Fedor Jelezko and colleagues implement a conditional two-qubit gate using an electron spin and a nearby carbon-13 nuclear spin associated with a nitrogen-vacancy defect in diamond.

Why it matters

A defect in diamond can support both controllable quantum bits and a logic operation between them, establishing a building block for spin-based processors.
