For a long time after the first large-scale computers, it was believed that entanglement, a purely quantum phenomenon, could be applied to information processing. Around 2000 the simplest quantum processors were fabricated, greatly reducing the number of iterations needed in certain famous algorithms. With the contemporary interest in quantum computing and quantum information, it is an exciting time to look for connections between information-theoretic concepts and other areas of quantum physics.
In this talk, after a brief overview of entanglement and quantum circuits, I will describe a specialized measure of quantumness that goes beyond entanglement, the so-called “magic”. Afterwards, I will present our latest work, focused on the production of “magic” in a set of tree-level 2-to-2 scattering processes under the electroweak theory and an extension of it.
