# qiskit.quantum_info.Statevector.from_instruction¶

classmethod Statevector.from_instruction(instruction)[소스]

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.
