Rolls-Royce says it is investing heavily now in quantum technology despite no quantum computers being available that can perform the calculations to a necessary standard.

It is between 3 and ten years away from 'advantage' and longer still from 'supremacy' but Rolls-Royce says it has to start now as it can take longer than that to get the algorithms correct .
