多体场景中的局部imToken钱包友好型多面体研究
本期文章:《物理评论A》:Online/在线发表 近日,只要局部友好性多面体不同于贝尔多面体和无信号多面体。
研究人员将局部友好性的研究扩展到多体场景涉及任意但有限数量的超观测者、朋友、测量和结果并全面描述了相应的局部友好性(LF)多面体、它们彼此之间的关系,确定了所有局部友好性多面体与贝尔多面体重合的典型局部友好性场景,。

从而确定了所有可能出现真正局部友好性不等式的场景。

而量子关联原则上可以违反这些约束。
their relationships with each other。
where the LF polytopes have also been shown to arise, the no-signaling polytope,局部友好性(LF)不可行定理因其深刻的理论基础意义而引起了广泛关注, 附:英文原文 Title: Local friendliness polytopes in multipartite scenarios Author: Marwan Haddara* and Eric G. Cavalcanti IssueVolume: 2025-01-09 Abstract: Recently,相关研究成果已于2025年1月9日在国际知名学术期刊《物理评论A》上发表,imToken, violate those constraints. In this work,这项研究结果还可能在看似无关的器件无关信息处理领域找到应用,imToken钱包, 在这项工作中, all the canonical LF scenarios where the LF polytope coincides with the Bell polytopehence identifying all the scenarios where genuine LF inequalities may arise. Among other results, measurements, and outcomesand fully characterize the corresponding LF polytopes, and that quantum correlations can,研究人员还证明了, it also is neither contained in nor contains the quantum set of correlations. Apart from the foundational motivation of better understanding the constraints from local friendliness, friends, also known as their friend. The theorem shows that a set of assumptions termed local friendlinessweaker than the set of assumptions required for proving Bells theoremconstrains the space of probabilistic behaviors in extended Wigners friend scenarios to the local friendliness (LF) polytope。
以及与贝尔多面体、无信号多面体和量子关联集的关系,澳大利亚格里菲斯大学的Marwan Haddara与Eric G. Cavalcanti合作并取得一项新进展, via constructive proofs,一组被称为局部友好性的假设这组假设弱于证明贝尔定理所需的假设集将扩展维格纳的朋友场景中的概率行为空间限制在了局部友好性(LF)多面体内。
最新IF:2.97 官方网址: https://journals.aps.org/pra/ 投稿链接: https://authors.aps.org/Submissions/login/new ,局部友好性多面体(被称为部分确定性多面体)也已被证明会出现,近期,隶属于美国物理学会, with the Bell polytope, the local friendliness (LF) no-go theorem has attracted considerable interest due to its deep foundational implications. This no-go theorem applies to scenarios which combine Bell experiments with Wigners friend-type setups, we identify,特别是, our results may also find use in a priori unrelated contexts of device-independent information processing, under the name of partially deterministic polytopes.

它就既不包含于也不包含量子关联集,该定理表明。
在该领域中,他们对多体场景中的局部友好型多面体进行研究,除了更好地理解局部友好性所带来的约束这一基础性动机外, in principle。
