    "abstract": "We consider the problem of decorrelating states of coupled quantum systems.\nThe decorrelation can be seen as separation of quantum signals, in analogy to\nthe classical problem of signal-separation rising in the so-called\ncocktail-party context. The separation of signals cannot be achieved perfectly,\nand we analyse the optimal decorrelation map in terms of added noise in the\nlocal separated states. Analytical results can be obtained both in the case of\ntwo-level quantum systems and for Gaussian states of harmonic oscillators.",
