A quantum trick with photons gives machine learning a speed boost

Machine learning, a process used to train artificial intelligences, can take an extremely long time – but a quantum trick could massively speed things up for tasks involving particles of light called photons

Quantum hyperchaos could help build better quantum computers

When quantum computers get too complex, they can display hyperchaotic behaviour – like chaos, but more chaotic – and understanding it could help improve computer designs
