Still looking for that elusive QC paper.
The one that explains how you can actually f**king program one of these things.
There "use case" is factorizing a 2048 prime which they say can be done in 110 days (which I think is pretty good given the conventional methods IIRC are still in the centuries at least).
Physicists. Yes it's clever, but WTF do we code it in? If you can't change the structure of the problem solved using code it's a plugboard program. Or in this case a "change the UHV module path"
Insofar as QC looks like normal programming it seems (loosely) to approximate "sieve" methods, where you generate all numbers and then apply a sieve function.
On the upside that would let you make a start of descrambling all the back episodes of Sky Digital people might have archived
In the QC case you seem to want random numbers or quantum states so you need a source of long wavelength radiation.
Hmm. Perhaps the radiation from a cooling cup of tea from the nearest drinks machine....
