Traditionally, photon scattering by an atom is considered to result-in decoherence. Can one nevertheless reverse this process? Using the information stored in the scattered photon we were able to coherently reverse the process in real time obtaining > 85 % correction fidelity whenever the photon was detected. We discuss the mechanism behind this reversal and show that the ion-photon interaction chooses a measurement basis for the ion, breaking the symmetry of the ion wave-function collapse.
