qiskit.quantum_info.Statevector.from_instruction¶
- classmethod Statevector.from_instruction(instruction)[source]¶
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.
- প্যারামিটার
instruction (qiskit.circuit.Instruction or QuantumCircuit) -- instruction or circuit
- রিটার্নস
The final statevector.
- রিটার্ন টাইপ
- রেইজেস
QiskitError -- if the instruction contains invalid instructions for the statevector simulation.
