Abstract

Boolean logic is an inherently irreversible, hence lossy operation. It has a well-known energy cost and an obvious time cost. To avoid those costs, we must do a different kind of logic. But, it is Boolean logic that we wish to do. We solved that dilemma by using a quantum optical logic gate that is fully reversible that yields the Boolean result after the irreversible loss of information in detection occurs.
