The + operator is no longer supported by QuantumCircuit:
In Section 2.3.6, the plus is used to concatenate circuits, altough this is no longer supported.
and += operators are no longer defined for QuantumCircuit.
Instead, you can use the & and &= operators respectively, which use QuantumCircuit.compose().
