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.　©　2023　Wiley-VCH　GmbH.
