Question

what are the observables in quantum mechanics?
​

Answer 1

Quantum mechanics. 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 dynamical variable represented by the observable can be measured as having.

Answer 2

An observable is an operator that corresponds to a physical quantity, such as. energy, spin, or position, that can be measured; think of a measuring device. with a pointer from which you can read off a real number which is the outcome. of the measurement. For a k-state quantum system, observables correspond.
