量子计算机模拟光合系统中的非辐射能量传递
Simulation of non-radiative energy transfer in photosynthetic systems using a quantum computer
摘要：
光合作用是自然界中一个重要而复杂的物理过程，对其的全面理解将具有许多相关的工业应用，例如在能源生产领域。在本文中，我们提出了一个量子算法的激子能量传输的模拟，发生在光合作用过程的第一阶段。该算法考虑了影响量子输运的量子效应和环境效应（纯退相）。我们在一台实际的5量子比特的量子计算机IBM Q中对这种现象进行了量子模拟，以证明概念方案。我们用Haken-Ströbl模型验证了结果，并讨论了环境参数对能量传输效率的影响。
英文摘要：
Photosynthesis is an important and complex physical process in nature, whose comprehensive understanding would have many relevant industrial applications, for instance in the field of energy production. In this paper we propose a quantum algorithm for the simulation of the excitonic transport of energy, occurring in the first stage of the process of photosynthesis. The algorithm takes in account the quantum and environmental effects (pure-dephasing), influencing the quantum transport. We performed quantum simulations of such phenomena, for a proof of concept scenario, in an actual quantum computer the IBM Q, of 5 qubits. We validate the results with the Haken-Ströbl model and discuss the influence of environmental parameters on the efficiency of the energy transport.
