An operator is a mathematical object that acts on a basis or state to produce another state. In quantum theory, operators represent physical quantities such as position, momentum, and energy.

Operators act on states to produce measurable quantities.
Quantum methods/operator.

Description

Operators encode the measurable properties of a system. Applying an operator to a state yields information about the corresponding physical quantity.

Properties

  • acts on states or functions
  • represents observables
  • central to quantum formalism
