Retro-information implies quantum unitary violation

Résumé

We prove simple theorems around the impossibility of sending information backward in time without the violation of the principle of quantum unitarity in physics. The result also extends to faster than light information transfer. The theorem is comparable to the "no-cloning" theorem, which we generalize. This result is a kind of reciprocal of the author former result which proved that a repetitive unitary violation would make possible retro-information.
