The article "Environment-Assisted Quantum Walks in Photosynthetic Energy Transfer" by Masoud Mohseni, Patrick Rebentrost, Seth Lloyd, and Alán Aspuru-Guzik explores the role of quantum interference effects in energy transfer dynamics within photosynthetic systems. The authors develop a theoretical framework based on continuous-time quantum walks, generalized to non-unitary and temperature-dependent dynamics in Liouville space, to study the interplay between free Hamiltonian and thermal fluctuations in the environment. They demonstrate that these effects can significantly enhance energy transfer efficiency from about 70% to 99% in the Fenna-Matthews-Olson (FMO) protein complex. The study uses a universal measure for energy transfer efficiency and its susceptibility to investigate the robustness and optimality of the transfer process. The results highlight the importance of quantum coherence and decoherence in enhancing energy transfer efficiency, providing insights into the underlying mechanisms of photosynthetic systems.The article "Environment-Assisted Quantum Walks in Photosynthetic Energy Transfer" by Masoud Mohseni, Patrick Rebentrost, Seth Lloyd, and Alán Aspuru-Guzik explores the role of quantum interference effects in energy transfer dynamics within photosynthetic systems.
