A quantum category   is defined as the (non-Abelian) category of quantum groupoids, Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "http://localhost:6011/en.wikiversity.org/v1/":): {\displaystyle [Q_{\grp}]_i}
, and quantum groupoid homomorphisms , Failed to parse (SVG (MathML can be enabled via browser plugin): Invalid response ("Math extension cannot connect to Restbase.") from server "http://localhost:6011/en.wikiversity.org/v1/":): {\displaystyle [q_{\grp}]_{ij}}
, where  and  are indices in an index class, , all subject to the usual ETAC axioms and their interpretations.

The category of quantum groupoids, Failed to parse (unknown function "\grp"): {\displaystyle [Q_{\grp}]_i} , is trivially a subcategory of the groupoid category, that can also be regarded as a functor category, or -category, if Failed to parse (unknown function "\grp"): {\displaystyle \grp} is small, that is, if is a set rather than a class.

A physical mathematics definition of quantum category has also been reported as a rigid monoidal category, or its equivalents.
