# qiskit.quantum_info.Statevector.from_instruction¶

classmethod Statevector.from_instruction(instruction)[Quellcode]

Return the output statevector of an instruction.

The statevector is initialized in the state $$|{0,\ldots,0}\rangle$$ of the same number of qubits as the input instruction or circuit, evolved by the input instruction, and the output statevector returned.

Parameter

instruction (qiskit.circuit.Instruction or QuantumCircuit) – instruction or circuit

Rückgabe

The final statevector.

Rückgabetyp

Statevector

Verursacht

QiskitError – if the instruction contains invalid instructions for the statevector simulation.
