Experimental Observation of Gravitational Bremsstrahlung: A Quantum Protocol using Levitated Nanodiamonds and Ultra-Relativistic Hadrons
Authors/Creators
Description
Abstract
This work details an experimental protocol for the direct observation of quantum
gravitational radiation (graviton emission). The experiment is based on the ”graz-
ing” interaction between ultra-relativistic hadron beams and an array of levitated
nanodiamonds. By integrating the spin-detection technique of Hoang et al. (2016)
with the fundamentals of gravity-mediated entanglement (Bose, 2017; Marletto,
2017), we propose a protocol that isolates the quadrupolar (spin-2) signature of
gravity from electromagnetic dipolar (spin-1) noise. The success of this experiment
would provide the first direct evidence of the corpuscular nature of gravity through
detection windows synchronized with high-energy accelerator infrastructure.We pro-
vide estimates for the event rate (∼1-5 Hz) and a hybrid shielding strategy to ensure
feasibility within high-energy accelerator environments.
