Simulation of depolarizing channel exploring maximally non separable spin-orbit mode

The Depolarizing channel is one of the most important noise models and constitutes a reliable benchmark for the quantum information field. In this work, we present a simple way to emulate a Depolarizing channel by exploring a maximally non separable spin-orbit mode in a compact linear optical circuit. The evolution of different states has been successfully reproduced. Our results are in excellent agreement compared with the results obtained by the spin-orbit Solovay-Kitaev decomposition for the Depolarizing channel, also presented here for the first time. Our proposal can be a powerful tool for studies of depolarizing effect.
