量子计算-P1.Ising Model与QUBO 前言: 在了解QUBO之前需要先了解伊辛模型(Ising Model,解释来源于维基百科),是一个以物理学家恩斯特·伊辛为名的数学模型,用于描述物质的铁磁性。 此模型中用于包含了可以用来描述单个原子磁矩的参数σi,其值只能为+1或-1,分别代表自旋向上或向下,这些磁矩通常会按照某种规则排列,...

而复杂系统更多的研究对象其实是动力学系统,这类系统往往都是处于非平衡态。另外,非平衡态的分析除了缺乏完善的基础理论之外,也没有像 Ising model 这样研究的非常透彻的经典系统作为toy model供科学家们把玩,所以重整化群相关的工作并不像平衡态系统那样丰富,更别提数据驱动相关的重整化建模工作了。

本文试图简要介绍一下Ising自旋玻璃(Ising spin glass)模型的相关数值方法,尤其关心怎么算基态能量和基态简并度(零点熵),包括 基于张量网络的方法。特点有 非常泛用 虽然是指数复杂度的,但是可以算得挺大 F. Barahona 等人在1980s,讨论计算复杂性时发展的方法 对平面图上的Ising spin glass model,显式给出了多项...
Obtaining a normalized maximum error < 1 is the most stringent statistical check of the inferred model performed by the ACE and QLS routines. It is possible to obtain a very good generative model of the data even in cases where this error is larger than 1 -- use QGT to verify an accept...
