von Neumann Architecture Demonstrated for a Quantum ComputerCategory: Science & Technology

At the heart of all processors is a single architecture, called the von Neumann architecture. This is the design that separates the arithmetic core of a processor from, memory, permanent storage and central control. Scientists at the University of California, Santa Barbara have successfully recreated this architecture with quantum circuits, essentially creating a quantum CPU. To test the device it was asked to run the quantum Fourier transform and a three-qubit Toffoli gate, which are key logic circuits that are needed for future quantum computing. I would recommend against waiting on your next upgrade for one of these.
