Entanglement in High-Energy Physics: An Overview

This abstract explores the entwined realms of quantum field theory, holography, and the AdS/CFT correspondence, converging upon the enigmatic phenomenon of entanglement within high-energy physics (HEP). At the core of this narrative lies the concept of entanglement entropy—a profound measure of quantum entanglement that threads the connections between quantum information, correlations, and the very architecture of spacetime. As the journey unfolds, the AdS/CFT correspondence illuminates entanglement’s holographic nature, decoding its role in deciphering the enigmas of HEP. Bell’s inequality emerges as a lighthouse, probing the non-local essence of entanglement and challenging the classical boundaries of reality. Quantum cryptography emerges as a practical extension, harnessing the unique attributes of entanglement for secure communication. The tensor product formalism weaves together the quantum tapestry, while gravity—nature’s sculptor of spacetime—molds the dynamics of entanglement within HEP. This abstract paves the path for a chapter that traverses based on original findings, unraveling the secrets of entanglement’s significance within the intricate fabric of high-energy physics. The Nobel Prize in Physics 2022, awarded to Alain Aspect, John F. Clauser, and Anton Zeilinger, enriches this narrative. Their experiments solidify entanglement’s non-locality, bridging the realms of quantum mechanics and HEP. This abstract encapsulates the entangled narrative and its dialog with gravity.
