Reversible computing is sort of hypothetical at heart. Besides cryptography and encoders, it’s mostly “if quantum computers eventually fit our model’s for reversible computing, then Landauer’s limit gives us energy-free computing as long as we never extract an answer!”
- klyrs 2y agoTechnically speaking, Landauer allows you to pay for extracted data on a bit-for-bit basis -- you don't need to pay for the whole computation as long as you're willing to spend approximately the same amount of time undoing it as you did doing it.
