CERN's ATLAS collaboration has made a significant breakthrough by observing quantum entanglement between top quarks at unprecedented energy levels using the Large Hadron Collider (LHC). This marks the first time such entanglement has been detected in a particle collider environment, specifically at an energy of 13 teraelectronvolts. The research, published in Nature, builds on previous findings from September 2023 and has been confirmed by the CMS collaboration. Quantum entanglement, a phenomenon where the state of one particle is linked to another regardless of distance, has implications for quantum computing and cryptography. The ATLAS and CMS teams utilized a novel method to analyze pairs of top quarks produced during proton-proton collisions, focusing on their spins and decay products. They found strong evidence of spin entanglement, with statistical significance exceeding five standard deviations. This discovery not only enhances the understanding of quantum mechanics but also opens avenues for testing the Standard Model of particle physics and exploring potential new physics beyond current theories.

I was under the impression that a particular entangled system is defined in terms of a particular waveform, which means that the choice of another waveform including, say, an additional particle off to the side, would imply that the entanglement -- which is supposed to be the behaviour being described, not the theory used to describe it -- actually changes. So, substitution of separate waveforms for each component of the entanglement would imply that entanglement is not present. How would this be false in a way different from the inaccuracies present in any other choice of waveform?
"Surely we're just a teensy bit away from that new physics, and if we can just a little bit more money^Wenergy into the system, we'll find that new physics for sure!"
