a classical quantization technique from signal processing that allows the modeling of probability density functions by the distribution of prototype vectors.

Error from rounding in digitization.

Difference between actual and represented values.

Second quantization, also referred to as occupation number representation, is a formalism used to describe and analyze quantum many-body systems.

(physics) The quantization of one or more components of the angular momentum of a system

In physics, canonical quantization is a procedure for quantizing a classical theory, while attempting to preserve the formal structure, such as symmetries, of the classical theory to the greatest extent possible.
