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).'"

    Tens of thousands of years of evolution and FINALLY are quantum computers can do the same level math as apes.

    Hazzah! Truly the golden era is upon us!

    Slashdot Disclaimer: I relize this is actually a very important and crucial step in quantum computing. ITS A JOKES

    So basically, -1 troll/offtopic is really slashdots way of saying "I hate that you thought of something before me."

    Non-native English speakers always seem to screw this up. "Math" is singular AND plural in English. Nobody who speaks English as a first language ever says "maths". If your problem involves calculus, geometry and algebra then your effort involves "doing the math". If you have more than one problem then the effort to solve them all involves "doing the math".

    "Maths" as a plural of something drives me up a wall. Almost as bad as "loose" instead of "lose", but non-native English speakers get a pass since they don't know any better. People who speak very good English non-natively all make this "maths" mistake. It's a sure way to tell if someone grew up speaking English or not.

    Sorry for the rant. Happy hoidays and peace to everyone. But remember, in English the term "math" is never pluralized by adding an "s" to the end just as the word "mathematics" is never used in the singular by removing the "s". There's no such thing as "maths" or "mathematic".

  3. sqrt(15)? by bosko0 · · Score: 0, Offtopic

    sqrt(15) = sqrt(5) * sqrt(3)

    Hmmm.. I bet they also calculated square roots of 9 and 25, but did not want to brag about it:

    sqrt(25) = sqrt(5) * sqrt(5)
    sqrt(9) = sqrt(3) * sqrt(3)
