摘要翻译:
我们提出了一种新的方法来研究$d$维经典系统的热力学性质,把这个问题归结为一个$d$维量子模型的基态性质的计算。这种经典到量子的映射允许我们在平等的基础上处理标准的优化方法,如模拟退火和量子退火。因此,我们将量子退火方法推广到有限温度下的经典系统。利用量子力学的绝热定理,我们导出了保证收敛到最优热力学状态的速率。对于模拟退火和量子退火,我们分别得到了温度和磁场的渐近速率$t(t)\pn)/(k_B\log t)$和$\gamma(t)\Nt\{-\bar{c}/N}$。还讨论了其他退火策略,以及它们的潜在加速。

英文摘要:
We present a new approach to study the thermodynamic properties of $d$-dimensional classical systems by reducing the problem to the computation of ground state properties of a $d$-dimensional quantum model. This classical-to-quantum mapping allows us to deal with standard optimization methods, such as simulated and quantum annealing, on an equal basis. Consequently, we extend the quantum annealing method to simulate classical systems at finite temperatures. Using the adiabatic theorem of quantum mechanics, we derive the rates to assure convergence to the optimal thermodynamic state. For simulated and quantum annealing, we obtain the asymptotic rates of $T(t) \approx (p N) /(k_B \log t)$ and $\gamma(t) \approx (Nt)^{-\bar{c}/N}$, for the temperature and magnetic field, respectively. Other annealing strategies, as well as their potential speed-up, are also discussed.
