论文摘要
Tavis-Cummings（TC）腔量子电动力学效应描述了$ N $原子与光学谐振器的相互作用，是原子，光学和固态物理学的核心。 TC动力学的完整数值模拟与原子的数量成倍缩放。通过将开放量子系统限制为单个激发，这是量子光学中实验实现的典型特征，我们可以分析用任意数量的具有线性复杂性的原子来求解TC模型。 This solution allows us to devise the Quantum Mapping Algorithm of Resonator Interaction with $N$ Atoms (Q-MARINA), an intuitive TC mapping to a quantum circuit with linear space and time scaling, whose $N+1$ qubits represent atoms and a lossy cavity, while the dynamics is encoded through $2N$ entangling gates.最后，我们基准在量子模拟器上对算法的鲁棒性进行基准，并针对经典计算机上的量子主方程解决方案对量子处理器进行超导。
Tavis-Cummings (TC) cavity quantum electrodynamical effects, describing the interaction of $N$ atoms with an optical resonator, are at the core of atomic, optical and solid state physics. The full numerical simulation of TC dynamics scales exponentially with the number of atoms. By restricting the open quantum system to a single excitation, typical of experimental realizations in quantum optics, we analytically solve the TC model with an arbitrary number of atoms with linear complexity. This solution allows us to devise the Quantum Mapping Algorithm of Resonator Interaction with $N$ Atoms (Q-MARINA), an intuitive TC mapping to a quantum circuit with linear space and time scaling, whose $N+1$ qubits represent atoms and a lossy cavity, while the dynamics is encoded through $2N$ entangling gates. Finally, we benchmark the robustness of the algorithm on a quantum simulator and superconducting quantum processors against the quantum master equation solution on a classical computer.
