entanglement_of_formation(state)[소스]¶ Calculate the entanglement of formation of quantum state.
The input quantum state must be either a bipartite state vector, or a 2-qubit density matrix.
- 매개변수
state (Statevector or DensityMatrix) – a 2-qubit quantum state.
- 반환값
The entanglement of formation.
- 반환 형식
float
- 예외
QiskitError – if the input state is not a valid QuantumState.
QiskitError – if input is not a bipartite QuantumState.
QiskitError – if density matrix input is not a 2-qubit state.
