What is the definition of a quantum gate? It is easy to find examples of quantum gates in the literature, but finding a good definition of just what a quantum gate is is a different story. I propose the following: " A quantum gate is a logically and thermodynamically reversible situation in which qubits of superimposed information can interact in a unitary fashion."
