Are problems in Quantum Information Theory (un)decidable? [article]

Michael M. Wolf, Toby S. Cubitt, David Perez-Garcia
2011 arXiv   pre-print
This note is intended to foster a discussion about the extent to which typical problems arising in quantum information theory are algorithmically decidable (in principle rather than in practice).  ...  We review some of the main tools for (dis)proving decidability and apply them to problems in quantum information theory.  ...  In the present paper we will, however, focus exclusively on problems occurring in quantum information theory. 1 Moreover, we will restrict ourselves to decidability problems and, for the moment, leave  ...

We are also indebted to Professor Grzegorz Rozenberg for publishing this group of papers in a Special Issue of the journal Natural Computing.  ...  The authors discuss the separation of the corresponding functional classes by quantum state identifications.  ...  The author shows how to use quantum measurements to test the (un)decidability of certain mathematical propositions, namely that elementary quantum systems are capable of encoding finite axioms, and quantum  ...

Intrinsic and Extrinsic Observation Mode [chapter]

Karl Svozil
2018 Physical (A)Causality  
Without epistemology any inroad into the subject of (un)decidability and (in)determinism may result in confusion and incomprehensibility.  ...  I strongly suspect that this simple fact is at the root of the measurement problem in quantum theory, in which the reversible dynamical laws cannot be used to describe the measurement process.  ...  Other eminent quantum physicists like Greenberger are proclaiming that "quantum mechanics is magic."  ...

Reachability analysis of quantum Markov decision processes

Shenggang Ying, Mingsheng Ying
2018 Information and Computation  
The (un)decidability and complexity of these problems are settled, or their relationships with certain long-standing open problems are clarified.  ...  It is shown by examples that qMDPs can be used in analysis of quantum algorithms and protocols.  ...  The (un)decidability and complexity of a series of reachability problems for qMDPs were settled, but several others left unsolved (the exact complexity of Problem 3.3.1 and the general case of Problem  ...

Quantum mechanics without interpretation [article]

O. Yaremchuk
2001 arXiv   pre-print
Quantum mechanics is one of these theories.  ...  Due to the structural inhomogeneity of the intermediate set, its complete description falls into several "sections" (theories) with their special main laws, dimensions, and directions, i.e., the complete  ...  Based only on the top view, the problem of separation (and even existence) of the black-and-white bricks of this kind is un-decidable. Each brick can be black-and-white with equal probability.  ...

Operational quantum logic: An overview [article]

2001 arXiv   pre-print
The term quantum logic has different connotations for different people, having been considered as everything from a metaphysical attack on classical reasoning to an exercise in abstract algebra.  ...  Our aim here is to give a uniform presentation of what we call operational quantum logic, highlighting both its concrete physical origins and its purely mathematical structure.  ...  This sustained interest reflects in part the fact that the basic ideas and language of quantum logic inform most discussions of the vexing foundational problems of quantum mechanics (indeed, to a degree  ...
