Testing phase estimation

See original GitHub issue

We are doing some sanity checks to see how phase estimation works and we cannot reconcile it with our expectations: the value of the estimation just does not match the correct value. Here’s a minimal working example.

Furthermore, if you change the phase to pi/8, the phase estimation fails all together, dropping ValueError: The wavefunction is not normalized.

The representation is as a binary fraction listed from the right. This means that 0001 represents 1/2 0010 represents 1/4 0011 represents 1/4 + 1/2 = 3/4 1000 represents 1/16

Each index to the left is 1/2^i

Does that makes sense @peterwittek ?
