    Bits and balls: Quantum computation is an island in theoryspace

    points on a ball, too. But in contrast to quantum bits, this ball does not need to be three-dimensional. What happens to computation if we allow the balls to have, say, dimension four or five? Two other IQOQI researchers, Borivoje Dakić and Ćaslav Brukner , have previously made a compelling conjecture: that these bits describe alternative physics in universes with more than three spatial dimensions. To check this idea, Krumm and Müller make two assumptions on how these bits ...

    Can the causal order between events change in quantum mechanics?
    09.04.2018
    conditions can this happen? Answers to these questions would be remarkable, because they would shed light on the nature of causality in the quantum world. In a recent paper, published in the journal Physical Review X, a group of physicists led by Časlav Brukner at the University of Vienna and the Vienna Institute for Quantum Optics and Quantum Information of the Austrian Academy of Sciences showed that, if the dynamics of causal structures is continuous and reversible, a ...

    Quantum causal relations: A causes B causes A
    03.10.2012
    objects can lose their well-defined classical properties, such as e.g. a particle that can be at two different locations at the same time. In quantum physics this is called a "superposition". Now an international team of physicists led by Caslav Brukner from the University of Vienna have shown that even the causal order of events could be in such a superposition. If - in our example - Alice and Bob have a quantum system instead of an ordinary piece of paper to write their ...

    In a quantum race everyone is both a winner and a loser
    29.03.2017
    physicists led by Philip Walther at the University of Vienna have implemented a new measurement, called a "causal witness", which allows them to watch Alice win and lose at the same time. This exciting measurement technique was designed by Caslav Brukner’s theory group at the Austrian Academy of Sciences. Formally, a causal witness is a mathematical tool to determine whether it is possible to describe an experiment without having to resort to superimposed orders. Using this ...
