    I think I can point out a couple of sentences.

    experiments show the D-Wave machines display quantum behaviour, it’s not clear this is responsible for speeding up computation.

    “My initial impression is that they looked to design a benchmark on which their machine has the best chance of succeeding,”

    outside experts contacted by New Scientist say the test is not a fair comparison.

    That's why I'm skeptical too... still, I'm glad some seriousness is been given to this issue

    I'm.... I don't know what to think... but considering that NASA and and Google are among its customers I think there has to be some seriousness behind their research.

    A new component that could eventually be a key participant in quantum computing has been developed:

    Did you just say the speed limit of light has been repealed?

    It appears so.

    It looks like, "Beam me up, Scotty" is on the horizon!

    Warp Speed may soon be a reality, but not in my lifetime.

    Noy really... that's just a quote from the article that I found interesting enough to post. And of course the article further down clarifies that that's not the case. But that it gives an illusion that the signal travels at an infinite speed.

    Interesting article. And at the bottom mentions the em drive that I was discussing in a previous post.
    Funny thing also is that history will probably remember that it was a mexican who first came up with a feasible scientific scenario for the development of a warp drive.

    GP? mind elaborating? On the other hand, are you saying that they're not quite yet there, but it's a step in the right direction?

    General Purpose computer. It's a step in proving we can use qubits for real logic circuits but a Quantum computer is not just a set of logic blocks chained like normal logic into registers, memory and an ALU. As more qubits are added the effort to keep entire quantum units logic state stable and free from errors the errors grow exponentially to the point you get errors every few operations. You can't clone qubits to generate normal error correction codes so they need to use several (inefficient) to represent one qubit and then compare to see if an error value is generated. I've seen costs of $10-billion to build the manufacture capability after maybe the 10+ years it will take to find solutions to the current problems for the 100s of encoded qubits needed for a general quantum computer algorithm.

    And now, scientist are trying to crowdsource quantum algorithms development through (what else?) a puzzle game!

    crowdfunding is another venue for both legitimate research and not so legitimate research. At least they are not draining on national resources chasing a dream.

    Man's Credulity is always present. Then again, PT Barnum is reputed to say "A fool and his money ..."

    I thought he said, "There's a sucker born every minute."
    "A fool and his money" directs my mind farther back in time. More like Aesop's Fables.
