NATURAL METRIC FOR QUANTUM INFORMATION THEORY

Information Theory Metric for Assembly Language

Hermitian metric on quantum spheres

The paper deal with non-commutative geometry. The notion of quantumspheres was introduced by podles. Here we define the quantum hermitianmetric on the quantum spaces and find it for the quantum spheres.

Supersymmetric Quantum Field Theory: Indefinite Metric

We study the recently introduced Krein structure (indefinite metric) of the N = 1 supersymmetry and present the way into physical applications outside path integral methods. From the mathematical point of view some perspectives are mentioned at the end of the paper.

Is Pseudo-Hermitian Quantum Mechanics an Indefinite-Metric Quantum Theory?

With a view to eliminate an important misconception in some recent publications, we give a brief review of the notion of a pseudo-Hermitian operator, outline pseudo-Hermitian quantum mechanics, and discuss its basic difference with the indefinite-metric quantum mechanics. In particular, we show that the answer to the question posed in the title is a definite No.

Natural Philosophy and Quantum Theory

We attempt to show how relationalism might help in understanding Bell’s theorem. We also present an analogy with Darwinian evolution in order to pedagogically explain Bell’s theorem.
