The modern quantum mechanical description says that light can also be considered to be particles called photons.
And, no attempt is made to provide a quantum description of the theory-this being left for future work.
The rapid rate at which quantum descriptions become more complicated as the size of a system increases.
The quantum description of imperfectly coherent paths is called a mixed state.
When they are later separated, they keep the same quantum mechanical description or "state."
Science has not yet unraveled a quantum description of gravity yet.
There is only an abstract quantum physical description.
That basic scaffolding remains when one moves to a quantum description but some conceptual changes are needed.
Fuzzball theory is thought by its proponents to be the true quantum description of black holes.
It is also used to differentiate between states of light that require a quantum mechanical description and those for which classical fields are sufficient.
