Description
Entangled quantum systems violate Bell's inequality. Quantum entanglement has been observed in photon systems through Bell's inequality test. Particle physicists have been interested in testing Bell's inequality at various particle colliders, e.g. through top quark pairs at the LHC, providing a new realm of entangled systems at much higher energies than previously observed. One such entangled system is neutral B meson pairs at B-factories. Belle Collaboration reported an observation of Bell's inequality violation in entangled B mesons [Go, 2003]. However, later theoretical work [Bramon etal, 2005] raised concerns about these results and claimed that Bell's inequality tests cannot be performed at particle colliders. We analyze the origin of this discrepancy in the literature by comparing the theoretical assumptions used in the two approaches.
