Quantum computers may be at least five years away from "commercial usefulness" but anticipation that a breakthrough could be imminent is growing within the sector.

The second is computation, which is where quantum computers come in.

Superconducting machines, on the other hand, although most advanced in engineering terms, require massive refrigeration systems for cooling, which means they score low for "commercial value", Mooter believes.

Sandhu decided to enter a quantum world, which is even more heavily male-dominated than the wider tech space, for various reasons.

Sandhu believes her dad's love of science and willingness to nurture her own love of it made a big difference for her here.
