Light-based Quantum Circuit Does Basic Maths

Posted by Zonk on from the small-steps-start-small dept.

Stochastism writes "In yet another small step toward realistic quantum computing Australian researchers have developed a light based 4-qubit quantum computer. It has already calculated the prime roots of fifteen, three and five. 'The quantum circuit pioneered by the Queensland researchers involves using a laser to send "entangled" photons through a linear optical circuit ... The Queensland research group acknowledged that the theorised code cracking ability of quantum computers may be why Australian quantum computer research is in part funded by a US government defence intelligence agency, the Defense Advanced Research Projects Agency (DARPA).'"

    I wonder if Moore's law will apply to the number of qubits within a quantum computer as well. A 1024 qubit computer within the next 20 years would be nice.

      Nobody would ever be able to use 1024 qubits.

    The similarity to bits only occurs once you open the box.
    Until that point a cubit represents a dead cat.

    I, too, have already calculated the prime roots of fifteen, with nearly identical results. Where's my DARPA funding?

    Q: What kind of room is it kept it?
    A: A Qubicle

    Q: How big is it?
    A: About four Qubit meters.

    Q: Qubit? Wasn't that an early arcade game with a little guy jumping around changing the quantum state of a bunch of Qubes?
