Quasiprobability distributions, sometimes colloquially referred to as "quasiprobability distributions," are mathematical objects that resemble probability distributions but do not strictly satisfy all the axioms of probability theory. Unlike true probability distributions, which must be non-negative and integrate to one, quasiprobability distributions can take on negative values or fail to normalize to one. Despite these deviations, they prove to be incredibly useful tools in various fields of physics and mathematics.
One of the primary applications of quasiprobability distributions is in quantum mechanics. In this context, they
Beyond quantum mechanics, quasiprobability distributions appear in other areas where classical probability theory faces limitations. For
