A PsiQuantum silicon wafer containing thousands of quantum devices
PsiQuantum
On a large table in front of me is some of the world’s most advanced photonic hardware, which may soon drive one of the great technological revolutions of our time. I can see tiny microchips that look like precious jewels, with nanoscale patterns that make them glow like rainbows, along with detectors, filters and switches connected by fibre-optic cables, laid out on smartphone-sized circuit boards. These are the fundamental components of a massive photonic quantum computer that could be up and running in just a few years – though to…
