Is Computing in Reverse the Next Big Thing?

As Moore’s Law runs out of steam, and fabrication of Boolean circuits on silicon appears to be reaching its limits, some computer scientists and physicists are looking beyond the limits of current computing to “reversible computing.” That is, instead of one-way circuits that produce a deterministic output from given inputs, reversible computing works both ways: Inputs can be obtained from outputs by running the circuits in reverse. Generally speaking, computation runs in one direction, producing outputs from inputs, without the ability to run backwards and compute inputs from outputs.
