In science:

Thus, depolarization can be associated with an increasing informational entropy.
Higher Order Statistsics of Stokes Parameters in a Random Birefringent Medium
In subsection 6.2, the L´evy process model was used to study the depolarization of a lightwave by propagation in a random birefringent medium.
Higher Order Statistsics of Stokes Parameters in a Random Birefringent Medium
It was shown that depolarization takes place independently of initial conditions.
Higher Order Statistsics of Stokes Parameters in a Random Birefringent Medium
Under the assumption that the noise model can be represented by a quantum operation acting independently between the implementations of U and U −1 , the effect of the randomization is to depolarize the noise.
Randomized Benchmarking of Quantum Gates
Note that the results of hold if the unitaries are restricted to the Clifford group, because the Clifford group already has the property that noise is depolarized.
Randomized Benchmarking of Quantum Gates
Suppose that all errors are independent and depolarizing.
Randomized Benchmarking of Quantum Gates
The state after Ak is a known eigenstate of a Pauli operator or completely depolarized.
Randomized Benchmarking of Quantum Gates
Depolarization of the state is equivalent to applying a random Pauli or identity operator, each with probability 1/4.
Randomized Benchmarking of Quantum Gates
The probability of the state’s not having been depolarized is Qk j=0(1 − dAj ).
Randomized Benchmarking of Quantum Gates

Randomized Benchmarking of Quantum Gates
This is given by the expectatio n over gates of 1 − Fa and relates to the depolarization parameter d of the previous paragraph by 1 − Fa = d/2.
Randomized Benchmarking of Quantum Gates
If the errors are independent and depolarizing, the pj,lk ,m and the pj,lk should not differ signi ficantly from the plk .
Randomized Benchmarking of Quantum Gates
In contrast, if the error is depolarizing, the pj,lk ,m are all close to 1/2 independent of j and m.
Randomized Benchmarking of Quantum Gates
