Quantum computing is an emerging technology that even excites smart prime ministers.

A quantum computer would eclipse even the fastest classical computers we have today. A reliable quantum computer capable of solving complex problems would have to consist of billions of quantum systems.

How to build them? Diamond and its nitrogen defects — otherwise the result of poor clarity and color in diamond gems — can store one quantum bit of information: zero, one, or an arbitrary superposition of both.
