In the paper by Stamatopoulos et al., the authors say that it is possible to load a distribution on a three qubit state to obtain:
In Qiskit finance this is performed using the uncertainty model function. My question is, how do you encode random numbers on qubit states?
Later is their paper they report that you can use controlled-Y rotations to load a random distribution, this way:
but I don't know how they pick the angle for the controlled rotation in order to obtain the desired number.
