Parameters

QuantumChannel (other (Operator or) – or Instruction or Circuit): The operator to evolve by.
qargs (list) – a list of QuantumState subsystem positions to apply the operator on.

Returns

the output quantum state.

Return type

QuantumState

Raises

QiskitError – if the operator dimension does not match the specified QuantumState subsystem dimensions.
