Path-integral formulation: Quantum field theory, Path integral in quantum mechanics & Quantum action principle

The path-integral formulation of quantum mechanics generalizes the action principle of classical mechanics. It replaces the classical notion of a single, unique classical trajectory for a system with a sum, or functional integral, over an infinity of quantum-mechanically possible trajectories to compute a quantum amplitude.
