    The Elusive Source of Quantum Speedup.Vlatko Vedral - 2010 - Foundations of Physics 40 (8):1141-1154.
    We discuss two qualities of quantum systems: various correlations existing between their subsystems and the distinguishability of different quantum states. This is then applied to analysing quantum information processing. While quantum correlations, or entanglement, are clearly of paramount importance for efficient pure state manipulations, mixed states present a much richer arena and reveal a more subtle interplay between correlations and distinguishability. The current work explores a number of issues related with identifying the important ingredients needed for quantum information processing. We (...)

  2. How Much of One-Way Computation Is Just Thermodynamics?Janet Anders, Michal Hajdušek, Damian Markham & Vlatko Vedral - 2008 - Foundations of Physics 38 (6):506-522.
    In this paper we argue that one-way quantum computation can be seen as a form of phase transition with the available information about the solution of the computation being the order parameter. We draw a number of striking analogies between standard thermodynamical quantities such as energy, temperature, work, and corresponding computational quantities such as the amount of entanglement, time, potential capacity for computation, respectively. Aside from being intuitively pleasing, this picture allows us to make novel conjectures, such as an estimate (...)
