NOT / INVERTER gate:

To complete a full set of logic gates, we need one more thing: A NOT (or INVERTER) gate.

The output of a NOT gate is the opposite of its input ("1" changes "0" or "0" changes to "1").

We cannot get this from a majority gate.

Instead we have to lay out QCA cells in the new pattern shown here.
