    "Quantum computing" on a Commodore 64



    There's a lot of other stuff more-or-less silly stuff here but the project description for the C64 quantum computing project starts on page 203.

    Here is the setup they used:

    Doesn't look like they are going to reach absolute zero that way...?

      They apparently built a cartridge to hold the program, which is one way to free up more ram in the computer to do the actual computation with. I wonder why they didn't put it on a floppy since you can do overlays from a disk file on a C64; it would naturally have been many times slower (since the 1541 is a notoriously slow drive due to its bus design) but it would have looked cooler and given the project that much more cachet.

      Oh well. What do I know....

        If only what they are doing was actually useful....?

            I thought the data on page 286 was useful...
