Quantum Gravity-Induced Entangled States Demonstrate Photon Emission Rates Linked to Entanglement Degree, Impacting Fundamental Mechanics Research

Entanglement, a cornerstone of modern physics, continues to fascinate researchers and drive innovation in fundamental theory, and a new study explores its behaviour in the context of gravity. Chi Zhang from Zhejiang Ocean University leads a team that investigates the properties of entangled states created through a proposed experimental scheme called Gravity Induced Entanglement of Masses. The research demonstrates a clear relationship between photon emission rates and the degree of entanglement, revealing that emission rates decrease as entanglement strengthens at close distances, before stabilising at larger separations. This discovery offers a potential pathway to detect entanglement using photon emission, opening exciting possibilities for probing the interplay between quantum mechanics and gravity.

Entangled Photons and Quantum Gravity Effects

Quantum entanglement, a fundamental concept in quantum mechanics, has attracted significant attention for its extraordinary nonlocality and potential applications in exploring fundamental physics. This work investigates how photon emission rates change within entangled states influenced by quantum gravity, a crucial area for understanding the interplay between quantum mechanics and gravity. The research establishes a theoretical framework to predict and analyse photon emission characteristics from entangled photon pairs created in the presence of quantum gravitational effects, revealing a quantifiable relationship between the phase of entangled photons and their emission probabilities. This study analyses the quantum properties of the entangled states generated in the QGEM scheme, revealing a close relationship between photon emission rates and the degree of entanglement. The team’s findings demonstrate a clear connection between photon emission rates and the degree of entanglement in particle pairs. Calculations reveal that as the distance between particles decreases, the transition rate diminishes with increasing entanglement, eventually stabilising at a value independent of entanglement as the distance grows. This suggests a potential method for detecting entanglement by analysing the emitted photons, offering an alternative to traditional entanglement witness techniques.

The study focused on the entangled states generated by the QGEM mechanism and how entanglement influences the spontaneous transition rates of particles. Through first-principles calculations, researchers were able to show how entanglement either suppresses or promotes transitions within the particle pair, providing insight into the dynamics of entanglement itself and offering guidance for future experimental designs. The authors acknowledge that current models, like those focusing solely on Newtonian gravity, may lack the necessary dynamical degrees of freedom to fully capture the observed effects, and that similar entanglement generation could be explained by alternative theoretical frameworks.
