Quantum scientists demonstrate world-first 3D atomic-scale quantum chip architecture

Scientists have shown that their pioneering single atom technology can be adapted to building 3D silicon quantum chips -- with precise interlayer alignment and highly accurate measurement of spin states. The 3D architecture is considered a major step in the development of a blueprint to build a large-scale quantum computer.
