Pauli propagation sample

[aromanro]

In the pauli propagation example each gate is executed in a for loop. At the end of the loop the views are swapped for the next iteration (so the 'in' one becomes 'out' and viceversa).

In order to preserve the last 'out' view as the 'out' view, after the for another swap is done:

cuQuantum/samples/cupauliprop/kicked_ising_example.cpp

Line 614 in 4e097de

std::swap(inExpansion, outExpansion);

This seems ok so far, but then when computing the expectation value, the 'in' view is used:

cuQuantum/samples/cupauliprop/kicked_ising_example.cpp

Line 631 in 4e097de

HANDLE_CUPP_ERROR(cupaulipropPauliExpansionGetNumTerms(handle, inExpansion, &numOutTerms));

Shouldn't be that replaced by the 'out' expansion?

Yes indeed, thanks for pointing this out! This will be fixed in an upcoming release.
