The Multifarious Quantum Information

The Multifarious Quantum Information This paper considers the scope and possibilities of quantum information within the consensus interpretation of the theory. It is pointed out that a prepared quantum state offers a multitude of answers determined by the query directed to it. It predicts the outcome of measurements of alternative observations or allows the performance of a selection of quantum information processes. Knowing the state does not determine which observables can be assigned values, but defining a point of view of the observer allows him to derive outcomes of measurements. However, all predictions are in the form of statistical distributions or correlations between observations. Thus they are intrinsically independent of separations in space and time: like all statistical knowledge they have to be reassessed when new infomation imposes a new initial state. Many properties determined by quantum observations must be assigned to the results of the measurements and not to the physical system itself. Thus the property of nonlocality is a consequence of the probabilistic interpretation only, and it corresponds to no feature assigned to the physical reality.
