The quantum dynamics of entanglement is widely revealed in photosynthetic light-harvesting complexes. Different from the previous work, we explore the properties of exciton transport and photosynthesis assisted by the quantum entanglement in two adjacent pigment molecules, which are measured by the population dynamics behaviors, the j-V characteristics and by the output power via a photosynthetic quantum heat engine model. A more robust exciton transport dynamic behavior is compared with those without quantum entanglement, and the photosynthetic characteristics evaluated by the output current and power were proved to be enhanced by the quantum entanglement at different ambient temperatures. These results may point toward the possibility for artificial photosynthetic nanostructures inspired by this quantum biological systems.
