Shadow Tomography utility functions

Functions

CUE(random_gen, n)

Prepares single qubit Haar-random unitary (drawn from Circuilar Unitary Ensemble - CUE).

get_local_shadow(counts, unitary_arg, ...[, ...])

Constructs shadows for each individual initialisation.

get_negativity(rho, NA, NB)

Computes the negativity of a given density matrix.

local_shadow_tomography(qc, Nu, active_qubits)

Prepares the circuits to perform local Haar or Clifford shadow tomography.
