Todo List

Global statevec_calcInnerProduct (Qureg bra, Qureg ket)

could even do the kernel twice, storing real in bra.reduc and imag in ket.reduc?

Global statevec_multiControlledMultiQubitUnitary (Qureg qureg, long long int ctrlMask, int *targs, int numTargs, ComplexMatrixN u)

refactor so that the 'swap back' isn't performed; instead the qubit locations are updated.

Global statevec_multiControlledTwoQubitUnitary (Qureg qureg, long long int ctrlMask, int targetQubit1, int targetQubit2, ComplexMatrix4 u)

refactor so that the 'swap back' isn't performed; instead the qubit locations are updated.

the double swap (q1,q2 to 0,1) may be possible simultaneously by a bespoke swap routine.
