EMERGENT GRAVITY SIGNATURES IN ANALOG QUANTUM SIMULATORS BEYOND STANDARD HOLOGRAPHY

Abstract

Quantum mechanics is still the most basic unsolved problem in theoretical physics, and the development of gravitational dynamics out of purely quantum mechanical systems has become its most experimentally accessible frontier. The article is a systematic theoretical and experimental study of emergent gravity signals in analog quantum simulators outside of the traditional Anti-de Sitter/Conformal Field Theory holographic setup in six different platform classes, including Bose-Einstein condensate systems, optical and photonic fiber analogs, polariton condensates, trapped-ion quantum processors, superconducting qubit arrays and optical lattice architectures. Based on a carefully filtered working sample of seventy-nine peer-reviewed publications published between 2020 and 2025, the study will use a stratified purposive sampling approach and a triangulated theoretical-computational-empirical research design to describe emergent gravitational signatures in three main observational domains, namely, thermal emission spectra at effective quantum horizons, entanglement entropy scaling exponents benchmarked against holographic and non-holographic theoretical predictions, and quantum information scrambling rates compared against the Maldacena-Shenker- The emergent gravity signature was found in thirty-one of thirty-two experimental data sets analyzed and had Bose-Einstein condensate platforms giving the best fit to Hawking thermal predictions with an average spectral deviation of 4.2 +- 1.1 percent. Entanglement entropy scaling measurements of the scaling of AdS-compatible holographic signatures on large-system platforms to sub-holographic emergent gravity regimes of finite-size discrete quantum architectures indicated that effective system size was the key control parameter of holographic emergence. It was found that the dynamics of de Sitter-like dynamics in driven condensate cosmological analogs and near-maximal black-hole-like scrambling in Sachdev-Ye-Kitaev trapped-ion platforms can be measured to distinguish between anti-de Sitter and de Sitter scrambling hierarchies in any system. These observations all point towards the fact that analog quantum simulation is now an essential empirical concept in quantum gravitational phenomenology beyond standard holography.
