Artistic representation of the implemented photonic experiment in which entanglement between the polarizations of single photons is mediated by the independent degree of freedom of the photon path. Notably, mediated entanglement represents a core principle of future experiments using massive particles, aiming to probe for the first time the quantumness of gravity. Credit: Federico Alfano
Researchers are making significant progress in the field of quantum gravity, aiming to reconcile Einstein’s theory of gravity with quantum mechanics. Recent experiments demonstrate the principles of gravity-mediated entanglement using photons, a breakthrough in testing theories like string theory and loop quantum gravity. These experiments could transform our understanding of the universe and support future theoretical frameworks.
