But mainly because a a Quantum computer is also a reversible computer: a classical reversible computer could do it at essentially no energy cost, using algorithms developed by

Almost entirely incorrect: look up reversible computing

1. You're a bit pretentious aren't ya? 2. Just because this method is suggests it would need 2^69 joules and your lack of a suggestion doesn't, does not make OP's method incorrect, just inefficient. 3. We've got 280 chars for a reason, explain your point.

ok, so what i hear is that this is technically possible, that it's only a matter of time until 69 spherical vacuum cleaners can be built, and we should consider 256-bit keys effectively broken. Did i get that right?

So if bit changes use energy, how does reversible computing "save" energy? Is it because the reverse result is already instantiated in the original result, or is there something else at work?
