Incompatibility of observables as state-independent bound of uncertainty relations
Incompatibility of observables as state-independent bound of uncertainty relations
For a pair of observables, they are called "incompatible", if and only if the commutator between them does not vanish, which represents one of the key features in quantum mechanics. The question is, how can we characterize the incompatibility among three or more observables? Here we explore one possible route …
