Quantum Harmonic Oscillator - Wikipedia - en.wikipedia.org  ## Metadata - Author: **en.wikipedia.org** - Full Title: Quantum Harmonic Oscillator - Wikipedia - Category: #articles - Tags: #physic - URL: https://en.wikipedia.org/wiki/Quantum_harmonic_oscillator ## Highlights - The quantum harmonic oscillator is the quantum-mechanical analog of the classical harmonic oscillator. Because an arbitrary smooth potential can usually be approximated as a harmonic potential at the vicinity of a stable equilibrium point, it is one of the most important model systems in quantum mechanics. Furthermore, it is one of the few quantum-mechanical systems for which an exact, analytical solution is known
