China-US chip war takes a quantum leap with breakthroughs declared on same day

The Chinese study used light to generate and control a network of interconnected quantum states, showing the potential to build a quantum network on a tiny chip – a crucial step towards a quantum-based internet where information is shared securely and efficiently.

One reviewer of the study called the achievement “an important milestone for scalable quantum information” and noted that similar experiments had previously been attempted in the US, Europe and Japan.

The technology moved closer to “harnessing millions of potential qubits working together to solve the unsolvable – from new medicines to revolutionary materials – all on a single chip”, the company wrote in a post on social media.
