Researchers at the University of New South Wales have made a world-first research breakthrough demonstrating quantum entanglement between two atoms, a crucial underpinning for scaling quantum computers. Entanglement between at least two qubits is the phenomena that enables information to be encoded on a quantum computer and the information to be processed. This was demonstrated by the UNSW-led team between two electrons on separate phosphorus atoms.The phosphorus atoms were implanted on a silicon chip similar to those in the computers and electronics of today, potentially enabling future manufacturing scale up using existing chip fabrication techniques.
