开放量子系统方法广泛应用于物理、化学和生物系统的描述。一个著名的例子是光合作用初始阶段的电子激发转移，其中收获的能量以非常高的效率转移到反应中心。这种传输受到结构化振动环境运动的影响，这使得在经典计算机上进行模拟的要求非常高。在这里，我们提出了一种具有精确设计的量子环境的复杂开放系统动力学的模拟量子模拟器。我们的装置基于超导电路，这是一项成熟的技术。作为一个例子，我们证明了模拟 Fenna-Matthews-Olson 光合复合体中的激子输运是可行的。我们的方法允许进行可控的单分子模拟和能量转移途径以及非马尔可夫噪声相关效应的研究。
Open quantum system approaches are widely used in the description of physical, chemical and biological systems. A famous example is electronic excitation transfer in the initial stage of photosynthesis, where harvested energy is transferred with remarkably high efficiency to a reaction center. This transport is affected by the motion of a structured vibrational environment, which makes simulations on a classical computer very demanding. Here we propose an analog quantum simulator of complex open system dynamics with a precisely engineered quantum environment. Our setup is based on superconducting circuits, a well established technology. As an example, we demonstrate that it is feasible to simulate exciton transport in the Fenna-Matthews-Olson photosynthetic complex. Our approach allows for a controllable single-molecule simulation and the investigation of energy transfer pathways as well as non-Markovian noise-correlation effects.
