# IntegerComparator.combine¶

IntegerComparator.combine(rhs)

Append rhs to self if self contains compatible registers.

Two circuits are compatible if they contain the same registers or if they contain different registers with unique names. The returned circuit will contain all unique registers between both circuits.

Return self + rhs as a new object.

Parameters

rhs (QuantumCircuit) – The quantum circuit to append to the right hand side.

Returns

Returns a new QuantumCircuit object

Return type

QuantumCircuit

Raises

QiskitError – if the rhs circuit is not compatible
