    "abstract": "An analysis of quantum measurement is presented that relies on an\ninformation-theoretic description of quantum entanglement. In a consistent\nquantum information theory of entanglement, entropies (uncertainties)\nconditional on measurement outcomes can be negative, implying that measurement\ncan be described via unitary, entropy-conserving, interactions, while still\nproducing randomness in a measurement device. In such a framework, quantum\nmeasurement is not accompanied by a wave-function collapse, or a quantum jump.\nThe theory is applied to the measurement of incompatible variables, giving rise\nto a stronger entropic uncertainty relation than heretofore known. It is also\napplied to standard quantum measurement situations such as the Stern-Gerlach\nand double-slit experiments to illustrate how randomness, inherent in the\nconventional quantum probabilities, arises in a unitary framework. Finally, the\npresent view clarifies the relationship between classical and quantum concepts.",
