The key objectives of the research are to test Bell inequalities and other predictions of quantum information at unprecedented high energies in qubit (top-pair) and qutrit (Higgs boson) systems. Quantum information studies such as these have never been explored at hadron colliders before and have never been explored anywhere at these energies. Furthermore, the Higgs component of the project will involve isolating the H->WW->lepton + jets final state, an as-yet untested and unobserved Higgs decay mode. The student will set up the entire analysis using data from the ATLAS detector, from event selection and uncertainty estimation, through to result interpretation and exploitation, including developing novel techniques to isolate the signal events and subtract background processes that are not of interest.

该研究的关键目标是测试铃铛不平等和其他对量子信息的预测，以量子（Top Pair）和Qutrit（Higgs Boson）系统中前所未有的高能。诸如此类的量子信息研究以前从未在强子山子上进行过探索，并且从未在这些能量的任何地方进行探索。此外，该项目的HIGGS组成部分将涉及隔离H-> ww-> Lepton + Jets最终状态，这是一种尚未测试和未观察到的Higgs衰减模式。学生将使用来自Atlas检测器的数据，事件选择和不确定性估计到结果解释和开发，包括开发新型技术来隔离信号事件和减去不感兴趣的背景过程，从而建立整个分析。
