arXiv:1204.0850 · doi:10.1103/PhysRevA.87.014301
Abstract
The depolarizing quantum operation plays an important role in studying the quantum noise effect and implementing general quantum operations. In this work, we report a scheme which implements a fully controllable input-state independent depolarizing quantum operation for a photonic polarization qubit.
