In this framework, the system's evolution can be predicted by tracing out the environmental degrees of freedom. Here, we establish a precise mapping between the global unitary dynamics and the quantum operation involving the system, wherein the system is a single qubit, and the environment is modeled as a discrete lattice space. This approach enables the implementation of arbitrary noise operations on single-polarization qubits using a minimal set of three liquid-crystal metasurfaces, whose transverse distribution of the optic axes can be patterned to reproduce the target process. We experimentally validate this method by simulating common noise processes, such as phase errors and depolarization. Besides providing a practical solution for quantum state purification, this work demonstrates a versatile approach for the simulation of open qubit dynamics, with potential implications for quantum error correction and environment-induced quantum phase transitions.en2643-156420252American Physical Societyhttps://creativecommons.org/licenses/by/4.0/Open quantum systemsPhotonicsQbitsNatural Sciences and Mathematics::539: Matter; Molecular Physics; Atomic and Nuclear physics; Radiation; Quantum PhysicsTechnology::621: Applied Physics::621.3: Electrical Engineering, Electronic Engineering::621.38: Electronics, Communications EngineeringComputer Science, Information and General Works::004: Computer SciencesJournal Articlehttps://doi.org/10.15480/882.1602310.1103/PhysRevResearch.7.02323610.15480/882.16023Di Colandrea, FrancescoFrancescoDi ColandreaJaouni, TareqTareqJaouniGrace, JohnJohnGracePaneru, DilipDilipPaneruArienzo, MirkoMirkoArienzoD'Errico, AlessioAlessioD'ErricoKarimi, EbrahimEbrahimKarimiJournal Article
