3D Atomic Quantum Chips and Advance to Eventual Large Scale Quantum Tech | NextBigFuture.com

Australia’s New South Wales scientists have adapted single atom technology to build 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. They aligned the different layers in their 3D device with nanometer precision – and showed they could read out qubit states with what’s called ‘single shot’, i.e. within one single measurement, with very high fidelity. “This 3D device architecture is a significant advancement for atomic qubits in silicon,” says Professor Simmons.
