* All of the protocols under this technique broadly have two methods of state estimation from measurements: Linear inversion and Maximum Likelihood estimation. Linear inversion process is mathematically simpler but sometimes the computed solution of the density matrix is not valid. Hence Maximum Likelihood estimation is preferred as it constructs the states which has a higher probability of being valid. | * All of the protocols under this technique broadly have two methods of state estimation from measurements: Linear inversion and Maximum Likelihood estimation.
