How quantum computers work: Explaining qubits to quantum superposition

Quantum computing promises to deliver processing power that surpasses current supercomputers. So far, however, they have only managed a few specialised computations.

London-based start-up Quantum Motion, has taken an approach that utilises an already well-tested and ubiquitous material: silicon to build its quantum computers. For Quantum Motion co-founder, John Morton, silicon allows fast and cheap manufacturing of quantum processors that could soon put the power of quantum computing in the palm of our hands. We visited their test facility to find out more.
