CM Evaluation

cm.printing_cms(n, vector)

Calculates the cumulation of the coefficient matrices values which is an invariant.

In fact, at first, from the input vector, all the flattenings are made. Then, a calculation is done from each of them. In the end, the invariant is just the sum of all the results.

Example:

>>> printing_cms(3, [1 / sqrt(2), 0, 0, 0, 0, 0, 0, 1 / sqrt(2)])
1

Parameters:

• n (int) – The number of qubits.

• vector (list[int]) – A list filled with the coefficients corresponding to the vector.

Returns:

int – The invariant.
