• Title: Towards precision holography
• Authors: Niko Jokela and Arttu P\"onni
• Abstract summary: In principle one should be able to recover the full geometry as encoded on the duals of the gravity of the spacetime. Even this requirement cannot be fulfilled with arbitrary precision simply due to the fact that the boundary data is inherently noisy. We present a statistical approach to bulk reconstruction from entanglement entropy measurements, which handles the presence of noise in a natural way.

• Abstract: A minimal requirement for any strongly coupled gauge field theory to have a classical dual bulk gravity description is that one should in principle be able to recover the full geometry as encoded on the asymptotics of the spacetime. Even this requirement cannot be fulfilled with arbitrary precision simply due to the fact that the boundary data is inherently noisy. We present a statistical approach to bulk reconstruction from entanglement entropy measurements, which handles the presence of noise in a natural way. Our approach therefore opens up a novel gateway for precision holography.

  We derive the fundamental precision limit, the extended channel quantum Cram'er-Rao bound, and the optimal protocol that attains it. We discuss how this non-Gaussian protocol could improve searches for quantum gravity, gravitational waves, and axionic dark matter.

• Fuzzy spacetime: fundamental limits of quantum-optical holographic bulk reconstruction [0.0]
  We realize a version of "short-distance physics corresponds to poor statistics" idea by Kempf. The "fuzziness" of spacetime that arise from operational measurement protocols can be given a holographic dual interpretation. The holographic interpretation necessitates metric reconstruction even in principle due to the universality of future infinity.

• The minimal length: a cut-off in disguise? [0.0]
  The minimal-length paradigm is a possible implication of quantum gravity at low energies. We show that this modification is equivalent to a cut-off in the space conjugate to the position representation. We find a direct relation between the ensuing bound in wave-number space and the minimal-length scale.

  It is paramount to have practical measurement strategies that can estimate incompatible parameters with best precisions possible. Here, we give a concrete way to find uncorrelated measurement strategies with optimal precisions. We show numerically that there is a strict gap between the previous efficiently computable bounds and the ultimate precision bound.

• The holographic entropy cone from marginal independence [0.0]
  We argue that the holographic entropy cone can be reconstructed from more fundamental data determined solely by subadditivity of quantum entropy. This recasting of the bewildering entanglement structure of geometric states into primal building blocks paves the way to distilling the essence of holography.

We show that there exists a gap between the fundamental limits and the performance of the computationally tractable method of Bello and Honorio.

• Shape Matters: Understanding the Implicit Bias of the Noise Covariance [76.54300276636982]
  Noise in gradient descent provides a crucial implicit regularization effect for training over parameterized models. We show that parameter-dependent noise -- induced by mini-batches or label perturbation -- is far more effective than Gaussian noise. Our analysis reveals that parameter-dependent noise introduces a bias towards local minima with smaller noise variance, whereas spherical Gaussian noise does not.

Our results show that quantum probes are convenient resources, providing potential enhancement in precision.
