It was thought for some time that they needed be turned to heat, but that's actually untrue. Using quantum gates, it is possible to do an arbitrary classical computation and recycle the anciliary bits.
- dmlerner 4y agoNeat! Any reference you could share for me to read more?
- sudosysgen 4y agoThere is a short but sufficient Wikipedia article on it - it is called uncomputation : https://en.wikipedia.org/wiki/Uncomputation?wprov=sfla1 https://en.wikipedia.org/wiki/Uncomputation?wprov=sfla1 The textbook I used in my quantum computing class dealt with the subject far better, but unfortunately it's not public yet :/
