Quantum Physics: A Case for Anti-Realism?

quantum physics: a case for anti-realism?

the aim of the present paper is to sbo» that anti-realism in science, 1vhich has a1;guab/y become more fashionable in recentyears, contrary to tuha: its proponents assert, cannot make use of quantum mechanics and its impressiue achievements as a frump card in justifying its claims. i will argue that scientific anti-realism far from providing scientific communiry with a progressive methodologica...

4 Quantum Algorithms : Applicable Algebra and Quantum Physics

Classical computer science relies on the concept of Turing machines as a unifying model of universal computation. According to the modern Church– Turing Thesis, this concept is interpreted in the form that every physically reasonable model of computation can be efficiently simulated on a probabilistic Turing machine. Recently this understanding, which was taken for granted for a long time, has ...

Cluster algorithms for quantum impurity models and mesoscopic Kondo physics

Nanoscale physics and dynamical mean-field theory have both generated increased interest in complex quantum impurity problems and so have focused attention on the need for flexible quantum impurity solvers. Here we demonstrate that the mapping of single-quantum impurity problems onto spin chains can be exploited to yield a powerful and extremely flexible impurity solver. We implement this clust...

1 Algorithms for Quantum Systems — Quantum Algorithms

Since the presentation of polynomial time quantum algorithms for discrete log and factoring [Sho94] it is generally accepted that quantum computers may—at least for some problems— outperform classical ones. But the field of quantum information processing does not only have implications for computational problems. Using quantum mechanical systems for information processing naturally leads to the...
