even if every digit of such a number was stored in a single Planck volume, the entire universe would be too small to represent such a number. But this man has factorized such a number on a mobile phone? Lol.
just a minor thing to point out which is no one knows the size of the entire universe or if it is finite or infinite but i get what you're saying. some numbers are big to write down. for us mere mortals...
I personally ignore most quantum computation because quantum computing is overhyped. Think about it. Quantum computing promises exceptional speedup for some specific problems. Reversible computing promises moderate speedup for all problems.
reversible computing sounds like even more a fantasy than quantum computers. just because you make a computer that is reversible doesn't guarantee it won't use electricity or even large amounts of it, i would think. i have no idea why something that is reversible would be faster than a conventional computer. so you have some explaining to do there

got any examples of reversible computers? probably not.
