AI 中文摘要
我们提出了一种量子计算框架,用于模拟与重离子碰撞相关的基于马尔可夫和非马尔可夫动力学的开放量子系统方法。为在量子计算机上模拟非马尔可夫演化,我们引入一个辅助两能级赝模,该赝模携带记忆信息并耦合到子系统和剩余马尔可夫热库。我们明确证明,对赝模求迹可重现具有精确记忆核的非马尔可夫演化。此外,在相关时间尺度层次下,赝模的量子电路构造平滑收敛到马尔可夫极限。对于给定的热库记忆核,我们的结果证明了马尔可夫和非马尔可夫动力学量子模拟的可行性,为未来研究重离子碰撞中的喷注、重夸克和夸克偶素等硬探针建立了框架。
英文摘要
We present a quantum computing framework for simulating open-quantum-system approaches based on Markovian and non-Markovian dynamics, which is relevant to heavy-ion collisions. To simulate the non-Markovian evolution on quantum computers, we introduce an auxiliary two-level pseudomode that carries the memory forward and couples to both the subsystem and the residual Markovian bath. We explicitly show that tracing out the pseudomode reproduces the non-Markovian evolution with the exact memory kernel. Moreover, in the relevant time scale hierarchy, the quantum circuit construction of the pseudomode smoothly converges to the Markovian limit. For a given bath memory kernel, our results demonstrate the feasibility of quantum simulations of both Markovian and non-Markovian dynamics, establishing a framework for future studies of hard probes such as jets, heavy quarks, and quarkonia in heavy-ion collisions.
