- Observability is a measure of how well internal states of a system can be inferred from knowledge of its external outputs. In control theory, the observability and controllability of a linear system are mathematical duals. The concept of observability was introduced by Hungarian-American engineer Rudolf E. Kálmán for linear dynamic systems.

See all on Wikipediahttps://en.wikipedia.org/wiki/ObservableIn physics, an observable is a physical quantity that can be measured. Examples include position and momentum. In systems governed by classical mechanics, it is a real-valued "function" on the set of all possible system states. In quantum physics, it is an operator, or gauge, where the property of the quantum state … See more
In quantum physics, observables manifest as linear operators on a Hilbert space representing the state space of quantum states. The eigenvalues of observables are real numbers that correspond to possible values the … See more
A crucial difference between classical quantities and quantum mechanical observables is that the latter may not be simultaneously measurable, a property referred to as complementarity. This is mathematically expressed by non-commutativity of … See more

Eine Observable (lateinisch observabilis ‚beobachtbar‘) ist in der Physik, insbesondere der Quantenphysik, der formale Name für eine Messgröße und den ihr zugeordneten Operator, die im Zustandsraum, einem Hilbertraum, wirken. Beispiele sind die Energie, die Ortskoordinaten, die Koordinaten des Impulses und die Komponenten des Spins eines Teilchens sowie die Pauli-Matrizen.
