Space from Hilbert space: Recovering geometry from bulk entanglement

ChunJun Cao, Sean M. Carroll, Spyridon Michalakis

We examine how to construct a spatial manifold and its geometry from the entanglement structure of an abstract quantum state in Hilbert space. Given a decomposition of Hilbert space $\mathcal{H}$ into a tensor product of factors, we consider a class of ``redundancy-constrained states'' in $\mathcal{H}$ that generalize the area-law behavior for entanglement entropy usually found in condensed-matter systems with gapped local Hamiltonians. Using mutual information to define a distance measure on the graph, we employ classical multidimensional scaling to extract the best-fit spatial dimensionality of the emergent geometry. We then show that entanglement perturbations on such emergent geometries naturally give rise to local modifications of spatial curvature which obey a (spatial) analog of Einstein's equation. The Hilbert space corresponding to a region of flat space is finite-dimensional and scales as the volume, though the entropy (and the maximum change thereof) scales like the area of the boundary. A version of the $\mathrm{ER}=\mathrm{EPR}$ conjecture is recovered, in that perturbations that entangle distant parts of the emergent geometry generate a configuration that may be considered as a highly quantum wormhole.

Title: Non-Standard Quantum State Representation: Entanglement-Driven Geometry

Jincheng Zhang

This paper investigates the potential of a novel quantum state representation, termed the "Geometry-Aware Entanglement Metric," to provide a deeper understanding of entanglement dynamics. Traditional quantum state representations often lack explicit incorporation of the geometry inherent in the entanglement space, hindering our ability to fully characterize and predict entanglement behavior. We propose a new representation that leverages the curvature of the entanglement space as a key metric, allowing for a more comprehensive analysis of entanglement correlations. The proposed metric, coupled with a refined entanglement analysis technique, offers a potential pathway to unlocking new insights into the fundamental properties of entanglement. This work addresses a long-standing challenge in quantum information theory by introducing a fundamentally different approach to representing and manipulating quantum states.

超空间几何的量子纠缠建模

Jincheng Zhang

This paper investigates the potential of utilizing super-space geometry as a framework for modeling quantum entanglement. Traditional entanglement theories primarily focus on particle interactions, while this work proposes a novel approach by embedding quantum entanglement within the structure of super-space geometry. We aim to develop a computational methodology that reveals the dynamic characteristics of entangled states through the lens of this geometric model. The core claim is that super-space geometry offers a unique and powerful means of capturing the non-local nature of quantum entanglement, providing a more precise and comprehensive understanding of its properties. This research explores the potential of this approach to address limitations in existing entanglement models.

We examine how to construct a spatial manifold and its geometry from the entanglement structure of an abstract quantum state in Hilbert space. Given a decomposition of Hilbert space H\mathcal{H}H into a tensor product of factors, we consider a class of ``redundancy-constrained states'' in H\mathcal{H}H that generalize the area-law behavior for entanglement entropy usually found in condensed-matter systems with gapped local Hamiltonians.
