Noise　is　often　considered　as　the　biggest　enemy　of　maintaining　quantum　entanglement.　However,　in　this　paper,　it　shows　quantum　entanglement　can　be　protected　by　introducing　extra　noises　to　a　quantum　system.　As　an　example,　the　dynamics　of　a　two-qubit　system　coupled　to　a　cavity　is　studied　under　the　influence　of　three　noises,　a　quantized　noise　from　the　leakage　of　the　cavity　and　two　classical　noises　in　the　couplings　between　the　two-qubit　system　and　the　cavity.　The　master　equation　beyond　the　Markov　approximation　is　derived　and　the　mechanism　of　the　entanglement　protection　is　analyzed　in　a　special　case　with　analytical　solutions.　In　short,　the　entanglement　loss　caused　by　the　dissipation　to　the　bath　might　be　weaken　by　introducing　high-frequency　classical　noises　properly.　The　numerical　simulations　not　only　confirm　the　feasibility　of　protecting　entanglement　by　noises　but　also　reveal　that　the　properties　of　the　classical　noises　have　a　significant　impact　on　the　performance　of　the　entanglement　protection.　Due　to　inevitable　interaction　with　noisy　environments,　quantum　systems　often　lose　their　entanglement　quickly.　Since　noise　is　ubiquitous,　an　intriguing　question　arises:　Is　it　possible　to　combat　a　noisy　environment　with　its　own　weapon,　namely,　noise?　This　article　explores　the　suppression　of　entanglement　loss　caused　by　a　noisy　environment　through　properly　introducing　additional　classical　noises.image
