Description
Quantum entanglement is a fundamental property of quantum mechanics. Recently, studies have explored entanglement in the $t\bar{t}$ system at the Large Hadron Collider. In this talk, I will first introduce the search for evidence of quantum entanglement in the semi-leptonic decay channel of $t\bar{t}$. We find that this channel is both easier to reconstruct
and has a larger effective quantity of data than the fully leptonic channel, which is 60% more sensitive to quantum entanglement and a factor of 3 more sensitive to Bell inequality violation. Beyond the collider search, I will discuss the physics meaning of such entangled states, and some recent progress.
