量子多体模拟中的腔辅助能量弛豫

Cavity-assisted energy relaxation for quantum many-body simulations

Jaeyoon Cho, Sougato Bose, M. S. Kim

摘要:

我们提出了一个能量弛豫机制,使强关联自旋系统衰减到它们的基态。这种弛豫是由腔量子电动力学相互作用和腔光子的衰变驱动的。结果表明,通过施加宽带驱动场,强关联系统可以被冷却,而不管其能级分布的具体细节。该方案在其他方面也有重要意义,如绝热量子计算和耗散系统中的稳态纠缠。

英文摘要:

We propose an energy relaxation mechanism whereby strongly correlated spin systems decay into their ground states. The relaxation is driven by cavity quantum electrodynamics interaction and the decay of cavity photons. It is shown that by applying broadband driving fields, strongly correlated systems can be cooled regardless of the specific details of their energy level profile. The scheme would also have significant implications in other contexts, such as adiabatic quantum computation and steady-state entanglement in dissipative systems.
