Describe the Issue!

Most of the functions in random_objects.py take an N input and an optional dims. Those input are redundant as the size (N) can be obtained from the dims. However the way they handle this inconsistent:

• Many functions, such as rand_super, rand_dm, check that the dims matches the size and raise an error if it doesn't.
• rand_dm_ginibre, rand_super_bcsz j

What is the expected enhancement?

The openQASM project should have release notes associated with each tagged release (see #321). These should contain a summary of all changes included in the prepared release (or the development branch). For ease (and distribution) of maintenance, we should consider using reno which has been used with success in Qiski

There's an obvious extension of ZMask() to "masked" S, T, and general PhaseRootN gates.ZMask() calculates parity of each masked permutation, and applies a -1 multiplicative factor if the parity is odd, achieving a batched set of masked Pauli Z gates. Similarly, for a general batched PhaseRootN gate, the effective extension of this parity calculation is to a ring with 2^(n+1) phas

Given a quantum state provided as a density matrix or vector, determine whether the state is NPT (has negative partial transpose). If some of the eigenvalues of the transpose of the density operator representing the state are strictly smaller than zero, we say the state is NPT.

Note: A state is NPT if it is not PPT, so this should be a direct if not is_ppt(...) function call. It's mostly jus

Now that Q# + Python can use project files for references, we should add them here so IntelliSense can work better :)
