    "abstract": "It is shown that a large class of weak disturbances on macroscopic quantum\nsuperpositions can be canceled by a probabilistic reversing operation on the\nsystem. We illustrate this for spin systems undergoing an Ising-type\ninteraction with the environment and demonstrate that both the fidelity to the\noriginal state and the purity of the amended state can simultaneously be\nincreased by the reversing operation. A possible experimental scheme to\nimplement our scheme is discussed.",
