Would this generate less heat? Heat is still a bottleneck in some ways right? What about size? Can we get smaller? Would we need semiconductors anymore?

- adgjlsfhk1 5y agoheat is just power. 10x less power is 10x less heat.
- goldenkey 5y agoIndeed. All electrical devices are just space heaters that do something logical with the electricity while it's heating up the wires :-)

- goldenkey 5y agoFrom what I understand, most of the energy loss of our current computers is not due to using irreversible logic, but rather the actual resistance of the materials. Once we have better materials or different paradigms like photonic computing, then it would make sense to implement the https://en.wikipedia.org/wiki/Toffoli_gate https://en.wikipedia.org/wiki/Toffoli_gate https://en.wikipedia.org/wiki/Fredkin_gate https://en.wikipedia.org/wiki/Fredkin_gate and whatnot. Btw, Fredkin and Toffoli, and the rest of the kings of reversible computing were big advocates of cellular automata ;-)
