    Silicon is not one of the leading modalities for quantum computers, but it has progressed a lot in the past ~2-3 years. Here are a few key advancements that have happened as of late:- Intel can now do 2D which means a Surface code can be run on these devices: https://arxiv.org/abs/2412.14918- HRL can now do 2D as well: https://arxiv.org/abs/2502.08861- They are solving the wiring problem: https://www.nature.com/articles/s41565-023-01491-3- Their interconnects are high fidelity: https://www.nature.com/articles/s41586-025-09827-w

    The engineering at those scales is pretty magical isn't it! Getting a whole bunch of individual atoms exactly where they want them. I wonder what the success rate is - i.e. how many do they build to get one working.

    Can it run Shor's?

    Ahh yes another quantum processor that creates noise.

    Quantum Computing is a scam.I have not seen any progress or breakthroughs in the QC field at all that are significant.If the only goal for QC is to try to run Shor's algorithm or to "try to break the bitcoin blockchain" then it is worse than useless.

    Quantum computers can almost, but not quite, factor numbers bigger than 10.Time for git to break all workflows by showing huge alerts if a server is using crypto not proven quantum-proof!
