The important bit: "The UNSW team has struck a A$83 million deal between UNSW, Telstra, Commonwealth Bank and the Australian and New South Wales governments to develop, by 2022, a 10-qubit prototype silicon quantum integrated circuit – the first step in building the world’s first quantum computer in silicon." So no, they haven't built a many-qubit general quantum computer.

There has been some slow but noticeable progress in building quantum computers using semiconductors. Researchers at Princeton were recently able to implement a two-qubit quantum gate in silicon [0]. [0]: https://arxiv.org/pdf/1708.03530.pdf https://arxiv.org/pdf/1708.03530.pdf

  I'm pretty sure that's not slow progress.

    It depends on what we mean by "slow progress". The physical implementation of a quantum computer in silicon was proposed in 1998 [0] and a two-qubit gate was recently performed on it. This is in contrast to the ion trap quantum computer, where a two-qubit gate was proposed and performed in 1995 [1]. On the other hand, superconducting quantum computers followed the same road that silicon is on right now. It took a couple of years for superconducting qubits to be robust enough to perform universal quantum computation, but it's progress has accelerated in the past couple of years. So this says nothing of how fast silicon quantum computers will progress in the future.

      I quit working at shoprite and now I make $35h - $80h...how? I'm working online! My work didn't exactly make me happy so I decided to take a chance on something new… after 4 years it was so hard to quit my day job but now I couldn't be happier. Heres what I do, •••••••••>>http://www.bosscyber.com http://www.bosscyber.com
