    On the Two Aspects of Time: The Distinction and its Implications. [REVIEW]L. P. Horwitz, R. I. Arshansky & A. C. Elitzur - 1988 - Foundations of Physics 18 (12):1159-1193.
    The contemporary view of the fundamental role of time in physics generally ignores its most obvious characteric, namely its flow. Studies in the foundations of relativistic mechanics during the past decade have shown that the dynamical evolution of a system can be treated in a manifestly covariant way, in terms of the solution of a system of canonical Hamilton type equations, by considering the space-time coordinates and momenta ofevents as its fundamental description. The evolution of the events, as functions of (...)

    A Relational Time-Symmetric Framework for Analyzing the Quantum Computational Speedup.G. Castagnoli, E. Cohen, A. K. Ekert & A. C. Elitzur - 2019 - Foundations of Physics 49 (10):1200-1230.
    The usual representation of quantum algorithms is limited to the process of solving the problem. We extend it to the process of setting the problem. Bob, the problem setter, selects a problem-setting by the initial measurement. Alice, the problem solver, unitarily computes the corresponding solution and reads it by the final measurement. This simple extension creates a new perspective from which to see the quantum algorithm. First, it highlights the relevance of time-symmetric quantum mechanics to quantum computation: the problem-setting and (...)

    Why Dont We Know What Mary Knows? Baars' Reversing the Problem of Qualia.A. C. Elitzur - 1997 - Journal of Consciousness Studies 4 (4):319.
    Baars’ Global Workspace theory suggests that consciousness functions as a gateway, facilitating focused access to any part of the brain. While this hypothesis does not address the ‘hard problems’, namely, the very nature of consciousness, it constrains any theory that attempts to do so and provides important insights into the relation between consciousness and cognition. Many questions have found new answers once they were turned upside down. In medicine, for example, important discoveries have been made when, instead of asking ‘Why (...)
