AI 中文摘要
我们借鉴特·胡夫特（'t Hooft）提出的全息原理的开创性表述，分析信息在量子引力中的方法论与概念性作用。我们认为，在特·胡夫特的研究及后续发展中，信息发挥着实质性的指导原则作用。我们区分这一作用的三个方面：第一，某一区域可存储的信息量的全息边界，作为理论选择标准，约束着可行的量子引力理论；第二，全息原理发挥理论等价性原则的作用：体理论与边界理论必须描述相同的物理内容，尽管特·胡夫特更推崇更基础、低维且可能具有确定性的边界描述；第三，信息的分布与编码将特·胡夫特的提议与当代关于体重构、全息量子纠错及ER=EPR的研究相联系，其中涌现的时空结构与纠缠及冗余模式相关。基于这三个作用，我们认为，纯粹的认识论或香农式的信息概念在该语境下是不充分的：我们进而勾勒出所谓最大概念与中间概念的区分，旨在把握全息量子引力中信息的方法论与解释性作用。因此，我们建议，在全息原理与量子引力的语境下，对信息作为解释指导原则的作用开展更系统的哲学处理是可取的。
英文摘要
We draw on 't Hooft's seminal formulation of the holographic principle to analyse the methodological and conceptual role of information in quantum gravity. We argue that, in 't Hooft's work and in later developments, information functions as a substantive guiding principle. We distinguish three aspects of this role: First, holographic bounds on the amount of information that can be stored in a region function as theory selection criteria that constrain viable quantum gravity theories. Second, holography functions as a principle of theoretical equivalence: the bulk and boundary theories must describe the same physical content, even though 't Hooft privileges a more fundamental, lower-dimensional, and potentially deterministic boundary description. Third, the distribution and encoding of information connect 't Hooft's proposals to contemporary work on bulk reconstruction, holographic quantum error correction, and ER=EPR, where emergent spacetime structure is tied to patterns of entanglement and redundancy. On the basis of these three roles, we argue that purely epistemic or Shannon-style conceptions of information are inadequate in this context: we instead outline a distinction between what we call maximal and intermediate conceptions that aim to capture the methodological and interpretative roles of information in holographic quantum gravity. We therefore suggest that, in the context of holography and quantum gravity, a more systematic philosophical treatment of the role of information as an interpretation-guiding principle would be desirable.
