Abstract

Revealing the role of quantum entanglement in charge-transport in the Photosystem II reaction center (PSII RC) is of great significance. In this work, we theoretically demonstrate that the robust quantum entanglement provides regulatory benefits to the charge-transport via a quantum heat engine (QHE) model with two absorbed photon channels. The calculation results manifest that the dynamic charge-transport and the steady-state photosynthetic properties of the PSII RC were enhanced by the intensity of quantum entanglement. Insight into the role of quantum entanglement in photosynthesis could motivate new experimental strategies for biomimetic photosynthetic devices in the future.
