mrmustard.physics.overlap(A, B)[source]
Calculates the overlap between two quantum states.
If the states are both pure it returns \(|<A|B>|^2\), if one is mixed it returns \(<A|B|A>\)
and if both are mixed it returns \(Tr[AB]\).
- Parameters:
-
- Returns:
the overlap between the two states
- Return type:
float
