我们介绍了一个通用的设置为基础的半导体量子点电连接到一个链的量子RLC电子电路的开放量子系统的动力学的模拟量子模拟。点被选择为处于自旋-电荷杂化的状态，以增强它们对RLC电路的灵敏度，同时减轻不想要的噪声的有害影响。在这种情况下，我们建立了一个实验上可实现的映射之间的混合系统和量子位耦合到热谐波环境的任意复杂性，使开放的量子系统的模拟量子模拟。我们评估模拟器的实用性，数值精确的仿真表明，实验装置可以忠实地模仿预期的目标，即使在其自然固有的噪声存在。我们进一步提供了一个详细的分析的物理要求的量子点和RLC电路需要实验实现这一建议，表明模拟器可以创建与现有技术。该方法可以准确地捕捉高度结构化的非马尔可夫量子环境中典型的光合作用和化学动力学的效果，并比传统的甚至量子计算具有更明显的潜在优势。该方案为基于半导体量子点的有效量子动力学模拟开辟了一条通用途径。
We introduce a general setup for the analog quantum simulation of the dynamics of open quantum systems based on semiconductor quantum dots electrically connected to a chain of quantum RLC electronic circuits. The dots are chosen to be in the regime of spin-charge hybridization to enhance their sensitivity to the RLC circuits while mitigating the detrimental effects of unwanted noise. In this context, we establish an experimentally realizable map between the hybrid system and a qubit coupled to thermal harmonic environments of arbitrary complexity that enables the analog quantum simulation of open quantum systems. We assess the utility of the simulator by numerically exact emulations that indicate that the experimental setup can faithfully mimic the intended target even in the presence of its natural inherent noise. We further provide a detailed analysis of the physical requirements on the quantum dots and the RLC circuits needed to experimentally realize this proposal that indicates that the simulator can be created with existing technology. The approach can exactly capture the effects of highly structured non-Markovian quantum environments typical of photosynthesis and chemical dynamics, and offer clear potential advantages over conventional and even quantum computation. The proposal opens a general path for effective quantum dynamics simulations based on semiconductor quantum dots.
