What Is The Origination Of Zero Point Energy

[GAGS]

Can Anybody Tell Me ,unlike Classical Mechanics What Is The Origination Of Zero Point Energy,in Quantum Mechanics?

one often starts to consider the so called Energy-time uncertainty principe, that you always have a spread in energy.

Then, since alomst all systems can be modelled as a harmonic oscillatior, the ground state energy of a quantum oscillator is used as the zero point energy of systems.
