Spin versus Magic: Lessons from Gluon and Graviton Scattering Open
The quantum property of non-stabiliserness, also known as magic, plays a key role in designing quantum computing systems. How to produce, manipulate and enhance magic remains mysterious, such that concrete examples of physical systems that…

Emergent symmetry in a two-Higgs-doublet model from quantum information and nonstabilizerness Open
Studies of scattering processes in scalar models with two Higgs doublets have recently hinted at a connection between the absence of flavor-space entanglement in Φ+Φ0 scattering and an emergent SO(8) symmetry in the scalar potential. We ex…
