Observables and Measurements
... In “traditional” quantum mechanics, a property of a system that we can measure is referred to as an observable, and is represented by a Hermitean operator. Thus, if a system is in a given state (a pure state |φi or a mixed state ρ), one can determine expectation values and uncertainties in this obse ...
