Decoherence, the measurement problem, and interpretations of quantum mechanics
TL;DR: In this paper, the decoherence program, including its more recent results, and its application and consequences are investigated in the context of the main interpretive approaches of quantum mechanics. But their implications for the quantum measurement problem have remained a matter of great controversy.

Models of Wave-function Collapse, Underlying Theories, and Experimental Tests
TL;DR: In this article, a review is given of an experimentally falsifiable phenomenological proposal, known as continuous spontaneous collapse, which is a stochastic nonlinear modification of the Schrodinger equation.

Quantum Models of Cognition and Decision
Jerome R. Busemeyer,Peter Bruza +1 more
- 26 Jul 2012
TL;DR: The foundations for modelling probabilistic-dynamic systems using two aspects of quantum theory, 'contextuality' and 'quantum entanglement', are introduced, which allow cognitive phenomena to be modeled in non-reductionist ways.
An Inferential Conception of Scientific Representation
TL;DR: The inferential conception captures the objectivity of the cognitive representations used by science, it sheds light on their truth and completeness, and it explains the source of the analogy between scientific and artistic modes of representation.

Quantum feedback: Theory, experiments, and applications
TL;DR: In this article, an introductory overview of the various ways in which feedback may be implemented in quantum systems, the theoretical methods that are currently used to treat it, the experiments in which it has been demonstrated to date, and its applications.

Simulating physics with computers
TL;DR: In this paper, the authors describe the possibility of simulating physics in the classical approximation, a thing which is usually described by local differential equations, and the possibility that there is to be an exact simulation, that the computer will do exactly the same as nature.
On the Generators of Quantum Dynamical Semigroups
TL;DR: In this paper, the notion of a quantum dynamical semigroup is defined using the concept of a completely positive map and an explicit form of a bounded generator of such a semigroup onB(ℋ) is derived.
Scheme for reducing decoherence in quantum computer memory
TL;DR: In the mid-1990s, theorists devised methods to preserve the integrity of quantum bits\char22{}techniques that may become the key to practical quantum computing on a large scale.

Experimental Test of Bell's Inequalities Using Time- Varying Analyzers
TL;DR: In this article, the relationship of linear polarizations of pairs of photons was measured with time-varying analyzers, and the results were in good agreement with quantum mechanical predictions but violate Bell's inequalities by 5 standard deviations.
