Examples
From the commutativity of kets with (complex) scalars now follows that : must be the identity operator, which sends each vector to itself.
However, since : the smallest eigen-number is 0, and : In this case, subsequent applications of the lowering operator will just produce zero kets, instead of additional energy eigenstates.
Linear operators seeAlso Linear operators acting on kets A linear operator is a map that inputs a ket and outputs a ket.
When employing the Poincaré sphere (also known as the Bloch sphere ), the basis kets ( and ) must be assigned to opposing ( antipodal ) pairs of the kets listed above.
