A universal protocol that inverts the evolution of a qubit with a high probability of success

"takes qubit and outputs same system in state would be if evolved backwards in time... setting target qubit on superposition flight paths performing quantum operations... whenever fails can correct and drive desired state... probability of success as high as we want... like to generalize this protocol to higher dimensional systems... looking into improving the success probability of the other protocols in the original paper, particularly SWAP protocols"
