顶夸克作为量子信息的探针

Top quarks as a probe to quantum information

Andrew Wildridge

摘要:

大型强子对撞机(LHC)产生的顶夸克对为高能量子信息理论提供了一个独特的窗口。对量子信息最普遍的测量之一是贝尔不等式的违反。我们将探讨什么是必要的观察违反贝尔不等式和依赖于这对顶夸克对的初始状态。此外,我们展示了如何在量子计算领域中更普遍地应用量子信息理论来执行初级顶点的离线重建。我们对量子退火器的运行参数进行了一些优化,并将其与非优化的性能进行了比较。最后,我们讨论了这两个主题的未来前景和要采取的步骤。

英文摘要:

Top quark pairs produced at the Large Hadron Collider (LHC) provide a unique window into quantum information theory at high energies. One of the most ubiquitous measurements of quantum information is the violation of Bell's inequality. We explore what would be necessary to observe a violation of Bell's inequality and the dependence of this on the initial state of the top quark pair. Furthermore, we show how a more general application of quantum information theory in the realm of quantum computing can be leveraged to perform offline reconstruction of primary vertices. We perform some optimizations of the running parameters of the quantum annealer and compare them to a non-optimized performance. Lastly, we discuss the future outlook of both these topics and the steps to be taken.
