mpsprep.helpers.mean_fractional_entropy(y_amp)[source]

Given an array of amplitudes y_amp that define the quantum state \(|y> = \sum_i y_{amp}[i] |i>\), this function returns the mean fractional entropy of \(|y>\).

Parameters
y_ampnp.ndarray

Array of amplitudes. Can be complex.

Returns
mean_fractional_entropyfloat

Mean fractional entropy of the amplitudes.
