  • Because the math checks out.

    For a high level description, QEC works a bit like this:

    10 qubits with a 1% error rate become 1 EC qubit with a 0.01% error rate.

    You can scale this in two ways. First, you can simply have more and more EC qubits working together. Second, you can near the error correcting codes.

    10 EC qubits with a 0.01% error rate become one double-EC qubit with a 0.0001% error rate.

    You can repeat this indefinitely. The math works out.

    The remaining difficulty is mass producing qubits with a sufficiently low error rate to get the EC party started.

    Meanwhile research on error correcting codes continues to try to find more efficient codes.















  • You don’t need to know the details of the CPU architecture and pipeline, just the instruction set.

    Memory addressing is barely abstracted in C, and indexing in some form of list is common in most programming languages, so I don’t think that’s too hard to learn.

    You might need to learn the details of the OS. That would get more complicated.


  • A quick search on EBay shows some results for $100. That’s also relying on the console to be in decent shape besides being heavily used, and you have to deal with getting a video adapter, which is like $20 for a cheap one or $100 for one with fancy features that makes it look nicer.

    $250 for a brand new product supporting modern features like HDMI, USB, and Bluetooth sounds reasonable. It’s got a built-in video filter system like the fancier adapters, and if it’s anything like their previous products, it will have support for mimicking other consoles of similar compute power (the original PlayStation 1 potentially?) I checked and their website says it won’t support this feature. However, it does mention it has support for the Expansion Pack, which is another ~$70 although it’s only needed for a handful of games.

    Their previous products have sold quite well, so there’s that.
