Quantum vs Singlet - What's the difference?

quantum | singlet |


In context|physics|lang=en terms the difference between quantum and singlet

is that quantum is (physics) involving quanta while singlet is (physics) a multiplet having a single member, especially a single spectroscopic peak.

As nouns the difference between quantum and singlet

is that quantum is while singlet is (uk|australian|irish|nigeria|new zealand) a vest; a sleeveless garment with a low-cut neck, often worn underneath a shirt.

As an adjective quantum

is of a change, sudden or discrete, without intermediate stages.
