  • Information scrambling vs. decoherence -- two competing sinks for entropy 

    Touil, Akram; Deffner, Sebastian (2020-08-12)
    A possible solution of the information paradox can be sought in quantum information scrambling. In this paradigm, it is postulated that all information entering a black hole is rapidly and chaotically distributed across ...
