I am using the quantum mathematicaMathematica package and am trying to do computations that require me to use the outer (tensor) products of Pauli matrices. I would define this as, for example, Subscript[[Sigma], 2][CircleTimes]Subscript[[Sigma], 3] Subscript[\[Sigma], 2]\[CircleTimes]Subscript[\[Sigma], 3] . 

However if I ask mathematicaMathematica to compute this, it only finds the matrix product of the two operators, not the outer (tensor) product. Does anyone know of a way to do this calculation with MathematicaMathematica still recognisingrecognizing the operators as Pauli matrices, i.e. rather than writing them in matrix form or in Dirac notation?

Outer product using the quantum mathematica package
