Coordinate Formalism in Abstract Hilbert Space: Kinematics of a Quantum Measurement
نویسنده
چکیده
Coordinate form of tensor algebra on an abstract (infinite-dimensional) Hilbert space is presented. The developed formalism permits one to naturally include the improper states in the apparatus of quantum theory. In the formalism the observables are represented by the self-adjoint extensions of Hermitian operators. The unitary operators become linear isometries. The unitary evolution and the nonunitary collapse processes are interpreted as isometric functional transformations. Several experiments are analyzed in the new context.

Coordinate formalism on abstract Hilbert space
Coordinate formalism on Hilbert manifolds developed in [1] is reviewed. The results of [1] are applied to the simpliest case of a Hilbert manifold: the abstract Hilbert space. In particular, functional transformations preserving properties of various linear operators on Hilbert spaces are found. Any generalized solution of an arbitrary linear differential equation with constant coefficients is ...
متن کاملPOVMs and Naimark ’ s theorem without sums Extended abstract
We introduce POVMs within the categorical quantum mechanical formalism in terms of †-compact categories [2,7,8,17]. Our definition is justified by two facts: i. we provide a purely graphical abstract counterpart to Naimark’s theorem, which establishes a bijective correspondence between POVMs and abstract projective measurements on an extended system; ii. in the category of Hilbert spaces and li...
متن کاملImportance of reversibility in the quantum formalism.
In this Letter I stress the role of causal reversibility (time symmetry), together with causality and locality, in the justification of the quantum formalism. First, in the algebraic quantum formalism, I show that the assumption of reversibility implies that the observables of a quantum theory form an abstract real C^{⋆} algebra, and can be represented as an algebra of operators on a real Hilbe...
متن کاملThe witness set of coexistence of quantum effects and its preservers
One of unsolved problems in quantum measurement theory is to characterize coexistence of quantum effects. In this paper, applying positive operator matrix theory, we give a mathematical characterization of the witness set of coexistence of quantum effects and obtain a series of properties of coexistence. We also devote to characterizing bijective morphisms on quantum effects leaving the witness...
متن کاملUnconditional no-hidden-variables theorem
We present ultimate version of no-hidden-variables theorem. We shall derive a proposition under the existence of the Bloch sphere in a single spin-1/2 system. The existence of a single classical probability space for measurement outcome within the formalism of von Neumann’s projective measurement cannot coexist with the proposition. Namely, we have to give up the existence of such a classical p...
