Fr.: ket  

In Dirac’s notation, a vector which describes the state of a quantum system, whether it is in a space of finite or infinite dimensions. A ket vector,
written as | A >, is the dual of the → bra. Like the bra, it appears as an incomplete → bracket expression.

See also: From -ket the second syllable in → bracket.
