The quantum computing revolution is upon us. Well, almost. It’s hard to have missed the headlines proclaiming the great power of the latest generation of quantum, their ability to outperform conventional computers , a property called quantum supremacy, and the huge promise of the years ahead.
But an important question remains — how are we going to build these devices? Quantum computers variously rely on photons and/or exotic states of matter trapped in magnetic fields at mind-numbingly cold temperatures. So it’s easy to imagine that quantum computing will require an entirely new industrial base founded on novel technologies.
