Detailed Description

template<int L, int R>
class quantumoperator::Sigma< L, R >

Stateless class implementing the unary quantumoperator $\ket{L}\bra{R}$.

The template parameters are eventually converted to runtime data when the Sigma::apply function is called. At that point, dimensionality errors are detected in debug mode.

Note
Sigma should perhaps inherit from DimensionsBookkeeper as this would allow for an earlier detection of dimensionality errors.

Direct-product operator for Sigma.

Together with its overloads, this operator aptly demonstrates the use of DirectProduct and the meaning of its template parameters.
