    "abstract": "A common framework for quantum mechanics, thermodynamics and information\ntheory is presented. It is accomplished by reinterpreting the mathematical\nformalism of Everett\u0027s many-worlds theory of quantum mechanics and augmenting\nit to include preparation according to a given ensemble. The notion of\n\\emph{directed entanglement} is introduced through which both classical and\nquantum communication over quantum channels are viewed as entanglement\ntransfer. This point is illustrated by proving the Holevo bound and quantum\ndata processing inequality relying exclusively on the properties of directed\nentanglement. Within the model, quantum thermodynamic entropy is also related\nto directed entanglement, and a simple proof of the second law of\nthermodynamics is given.",
