entanglement_of_formation

entanglement_of_formation(state, d0, d1=None)

Compute the entanglement of formation of quantum state.

The input quantum state must be either a bipartite state vector, or a 2-qubit density matrix.

Parameters

• state (array_like) – (N) array_like or (4,4) array_like, a bipartite quantum state.
• d0 (int) – the dimension of the first subsystem.
• d1 (int or None) – the dimension of the second subsystem.

Returns

The entanglement of formation.

Return type

float
