VectorStateFn.compose¶
- VectorStateFn.compose(other)¶
Composition (Linear algebra-style: A@B(x) = A(B(x))) is not well defined for states in the binary function model, but is well defined for measurements.
- Parameters
other (
OperatorBase) – The Operator to compose with self.- Return type
- Returns
An Operator equivalent to the function composition of self and other.
- Raises
ValueError – If self is not a measurement, it cannot be composed from the right.
