One of the most promising ways to capture, generate and manipulate photons is with tiny diamonds. The secret is to create nanodiamonds with a defect in their structure where a nitrogen atom has taken the place of a carbon.
Quantum physicists are particularly interested in these so-called nitrogen vacancies because they can capture, store and emit the quantum information that photons carry. What’s more, they do all this at room temperature. It is even possible to manipulate this information using magnetic and electric fields.
