Decoherence and double-slit with eraser

  1. Jul 23, 2015 #1
    If I say that decoherence is an irreversible loss of information, then in the double-slit with erasure when initially decoherence has occured with the measurement, and then after erasure of the information the state is again as it was at the beginning , how can this occur if the initial decoherence was irreversible?

    You can say that - but that is not what decoherence is.

    All the erasure experiment shows is in simple cases decoherence is reversible.

    Thanks
