Physicists Chris D. White and Martin J. White reveal that the Large Hadron Collider (LHC) naturally generates "magic" top quarks—a quantum property essential for quantum computers to outperform classical systems. The study bridges quantum computing and high-energy physics, showing top quark pairs produced at the LHC exhibit quantum "magic," a resource critical for fault-tolerant quantum computation and speedups. This discovery transforms the LHC into a testbed for studying magic states, offering a high-energy environment to explore how quantum advantage arises in fundamental particle interactions. The research addresses an open challenge: how to create and amplify magic in quantum systems, with top quarks providing a novel, experimentally accessible platform. Funded by the Australian Research Council and UK’s STFC, the work suggests particle colliders could accelerate quantum computing advancements by probing magic’s origins in nature.

In this proceeding, I will review another interesting property from quantum computing ("magic"), that is needed to make quantum computers with genuine computational advantage over their classical counterparts. How to make and enhance magic in general quantum systems is an open question, such that new insights are always useful. To this end, we will show that the LHC naturally produces magic top quarks, providing a novel playground for further study in this area. × TY - JOURPB - SciPost FoundationDO - 10.21468/SciPostPhysProc.18.017TI - The magic of top quarksPY - 2026/01/29UR - https://scipost.org/SciPostPhysProc.18.017JF - SciPost Physics ProceedingsJA - SciPost Phys.
