<p>This calls swapQubitAmps only when it would involve a distributed communication; if the qubit chunks already fit in the node, it operates the unitary direct. </p>
<p>Note the order of q1 and q2 in the call to twoQubitUnitaryLocal is important.</p>
<p>@TODO: refactor so that the 'swap back' isn't performed; instead the qubit locations are updated. @TODO: the double swap (q1,q2 to 0,1) may be possible simultaneously by a bespoke swap routine. </p>
