Geometry of spacetime from quantum measurements

چکیده
We provide a setup by which one can recover the geometry of spacetime from local measurements quantum particle detectors coupled to field. Concretely, we show how field's correlation function on detectors. Then, are able invariant interval measurement outcomes, and hence reconstruct notion metric. This suggest that experimentally accessible devices could replace classical 'rulers' 'clocks' general relativity.

Quantum measurements and finite geometry
A complete set of mutually unbiased bases for a Hilbert space of dimension N is analogous in some respects to a certain finite geometric structure, namely, an affine plane. Another kind of quantum measurement, known as a symmetric informationally complete positive-operator-valued measure, is, remarkably, also analogous to an affine plane, but with the roles of points and lines interchanged. In ...
متن کاملFractal Geometry of Quantum Spacetime at Large Scales
We compute the intrinsic Hausdorff dimension of spacetime at the infrared fixed point of the quantum conformal factor in 4D gravity. The fractal dimension is defined by the appropriate covariant diffusion equation in four dimensions and is determined by the coefficient of the Gauss-Bonnet term in the trace anomaly to be generally greater than 4. In addition to being testable in simplicial simul...
متن کاملArithmetic Spacetime Geometry from String Theory
An arithmetic framework to string compactification is described. The approach is exemplified by formulating a strategy that allows to construct geometric compactifications from exactly solvable theories at c = 3. It is shown that the conformal field theoretic characters can be derived from the geometry of spacetime, and that the geometry is uniquely determined by the two-dimensional field theor...
متن کاملNonstandard optics from quantum spacetime
We study light propagation in the picture of semi-classical space-time that emerges in canonical quantum gravity in the loop representation. In such picture, where space-time exhibits a polymerlike structure at microscales, it is natural to expect departures from the perfect non-dispersiveness of ordinary vacuum. We evaluate these departures, computing the modi cations to Maxwell's equations du...
متن کاملTime, Consciousness and Quantum Events in Fundamental Spacetime Geometry
1. Introduction: The problems of time and consciousness What is time? St. Augustine remarked that when no one asked him, he knew what time was; however when someone asked him, he did not. Is time a process which flows? Is time a dimension in which processes occur? Does time actually exist? The notion that time is a process which "flows" directionally may be illusory (the "myth of passage") for ...
