A team in China has demonstrated that it has the world's most powerful quantum computer, leapfrogging the previous record holder, Google
21 June 2021
A secure quantum link has been created between two Chinese cities, allowing researchers to send entangled photons more than 500 kilometres using a relay hub in the middle that doesn't need to be trusted
