Three-qubit quantum processor (visualisation) (IMAGE) University of New South Wales Caption A visualisation of UNSW’s three-qubit system, which can perform quantum logic operations with over 99% accuracy. (Quantum operation fidelities above 99% were obtained in a three-qubit silicon quantum processor. The first two qubits (Q1, Q2) are the nuclear spins of individually-implanted phosphorus atoms (red spheres). The third qubit (Q3) is the spin of an electron that wraps around both nuclei (shiny ellipse).) Credit Tony Melov / UNSW Usage Restrictions Credit must be given to the creator.
