Qué (quién) es operator valued - definición

MEASURE WHOSE VALUES ARE POSITIVE SEMI-DEFINITE OPERATORS ON A HILBERT SPACE

Positive operator value measure; Positive operator-valued measure; Positive operator valued measure; Positive-operator valued measure

POVM

In functional analysis and quantum measurement theory, a positive operator-valued measure (POVM) is a measure whose values are positive semi-definite operators on a Hilbert space. POVMs are a generalisation of projection-valued measures (PVM) and, correspondingly, quantum measurements described by POVMs are a generalisation of quantum measurement described by PVMs (called projective measurements).

Many-valued logic (also multi- or multiple-valued logic) refers to a propositional calculus in which there are more than two truth values. Traditionally, in Aristotle's logical calculus, there were only two possible values (i.

Transfer operator

PUSHFORWARD ON THE SPACE OF MEASURABLE FUNCTIONS

Ruelle operator; Perron-Frobenius operator; Perron-Frobenius Operator; Frobenius-Perron operator; Bernoulli operator; Ruelle-Frobenius-Perron operator; Frobenius–Perron operator; Perron–Frobenius operator

In mathematics, the transfer operator encodes information about an iterated map and is frequently used to study the behavior of dynamical systems, statistical mechanics, quantum chaos and fractals. In all usual cases, the largest eigenvalue is 1, and the corresponding eigenvector is the invariant measure of the system.

POVM

In functional analysis and quantum measurement theory, a positive operator-valued measure (POVM) is a measure whose values are positive semi-definite operators on a Hilbert space. POVMs are a generalization of projection-valued measures (PVM) and, correspondingly, quantum measurements described by POVMs are a generalization of quantum measurement described by PVMs (called projective measurements).

In rough analogy, a POVM is to a PVM what a mixed state is to a pure state. Mixed states are needed to specify the state of a subsystem of a larger system (see purification of quantum state); analogously, POVMs are necessary to describe the effect on a subsystem of a projective measurement performed on a larger system.

POVMs are the most general kind of measurement in quantum mechanics, and can also be used in quantum field theory. They are extensively used in the field of quantum information.
