We show that perfect quantum teleportation can be achieved with mixed photonpolarization states when nonlocal memory effects influence the dynamics of thequantum system. The protocol is carried out with a pair of photons, whoseinitial maximally entangled state is destroyed by local decoherence prior toteleportation. It is demonstrated that the presence of strong nonlocal memoryeffects, which arise from initial correlations between the environments of thephotons, allow to restore perfect teleportation. We further analyze how theamount of initial correlations within the environment affects the fidelity ofthe protocol, and find that for a moderate amount of correlations the fidelityexceeds the one of the previously known optimal teleportation protocol withoutmemory effects. Our results show that memory effects can be exploited inharnessing noisy quantum systems for quantum communication and thatnon-Markovianity is a resource for quantum information tasks.
