标题： The role of the multiple excitation manifold in a driven quantum simulator of an antenna complex

摘要： 生物分子光捕获天线在相干相互作用的个体光、物质和振动量子非微扰强烈的尺度下作为纳米级装置运行。 由此产生的复杂行为，如果完全理解，可以用于多种能源应用。 然而，非微扰动力学在计算上具有挑战性，而对生物材料的实验仅探索了非微扰参数空间的非常有限区域。 所谓的光捕获模型“量子模拟器”可能为这一问题提供解决方案，这里我们采用层次化运动方程技术来研究Poto{č}nik$\it{et}$ $\it{al.}$ （Nat. Com. 9, 904 (2018)) 的最近超导实验，用于探索激子能量捕获。 通过明确包括光学驱动场的作用、非微扰去相位噪声以及三量子比特量子电路的完整多激发希尔伯特空间，我们预测了这些因素对传输效率的可测量影响。 通过对网络本征谱的分析，我们发现了一种允许网络利用光学“暗”态和激发态吸收进行能量传递的能量水平结构。 我们还确认，在驱动场和光学场的强非加性作用下，时间分辨的相干振荡仍可在实验中观察到。 显示英文摘要

摘要： Biomolecular light-harvesting antennas operate as nanoscale devices in a regime where the coherent interactions of individual light, matter and vibrational quanta are non-perturbatively strong. The complex behaviour arising from this could, if fully understood, be exploited for myriad energy applications. However, non-perturbative dynamics are computationally challenging to simulate, and experiments on biomaterials explore very limited regions of the non-perturbative parameter space. So-called `quantum simulators' of light-harvesting models could provide a solution to this problem, and here we employ the hierarchical equations of motion technique to investigate recent superconducting experiments of Poto{\v{c}}nik $\it{et}$ $\it{al.}$ (Nat. Com. 9, 904 (2018)) used to explore excitonic energy capture. By explicitly including the role of optical driving fields, non-perturbative dephasing noise and the full multi-excitation Hilbert space of a three-qubit quantum circuit, we predict the measureable impact of these factors on transfer efficiency. By analysis of the eigenspectrum of the network, we uncover a structure of energy levels that allows the network to exploit optical `dark' states and excited state absorption for energy transfer. We also confirm that time-resolvable coherent oscillations could be experimentally observed, even under strong, non-additive action of the driving and optical fields.
