论文摘要
我们提出了一个被困的离子平台，以模拟与量子热力学过程相关的可重构自旋旋转型汉密尔顿。 从一个实验模型开始，该模型在略有控制的驾驶阶段略有抗谐振的第一边带驾驶中描述了两个被困的离子，我们遵循一种操作量子光学的方法，表明它会产生在最近的量子热力学建议中出现的有效模型。 我们表明，投射到振动基态歧管中可以进行完全的分析处理。 作为一个实际的例子，我们从$^{187} $ yb $^{+} $陷阱中获取实验数据，并数值模拟了两个由量子相关控制的热旋转之间的热流量的逆转。
We propose a trapped-ion platform to simulate a reconfigurable spin-spin Hamiltonian related to quantum thermodynamic processes. Starting from an experimental model describing two trapped-ions under slightly off-resonant first sideband driving with individually controlled driving phases, we follow an operational quantum optics approach to show that it produces an effective model appearing in recent quantum thermodynamics proposals. We show that projection into the vibrational ground state manifold allows full analytic treatment. As a practical example, we take experimental data from a $^{187}$Yb$^{+}$ trap and numerically simulate the reversal of heat flow between two thermal spins controlled by their quantum correlations.
