Quantum Computers already exist, but not in the "universal" form that would truly revolutionize computing. That's why the latest innovation from Bristol University has so much promise: a team from its center for Quantum Photonics has built a reprogrammable quantum chip. The 70mm x 3mm box is capable of measuring and manipulating entanglement and mixture -- fundamental elements of the mythical "universal" chip. It's taken the team six years to reach this point, but now it'll concentrate on scaling up the technology to create more comple
