Description

In quantum computing, non-stabilizerness -- the magic -- refers to the computational advantage of certain quantum states over classical computers and is an essential ingredient for universal quantum computation. We study the production of magic states in Quantum Electrodynamics (QED) via 2-to-2 scattering processes involving electrons and muons. Considering all 60 stabilizer initial states, which have zero magic, the angular dependence of magic produced in the final states is governed by only a few patterns. It turns out QED is not very efficient in generating non-stablizerness and, in most cases, the largest magic generated is significantly less than the maximal possible value for two-qubit systems. Our results raise the question of whether quantum advantage is a fundamental property of basic forces or an emergent phenomena of many-body systems. We will also discuss hints that the Standard Model of particle physics is quite special from the computational viewpoint.
