Analytic formulae for non-local magic in bipartite systems of qutrits and ququints
Giorgio Busoni, John Gargalionis, Ewan N. V. Wallace +1
We conjecture analytic expressions for the non-local magic of bipartite pure qudit states of prime local dimension. Our construction relies on the Schmidt-aligned state attaining t…
Non-local nonstabiliserness in Gluon and Graviton Scattering
John Gargalionis, Nathan Moynihan, Michael L. Reichenberg Ashby +3
The property of non-stabiliserness, or ``magic'', is of interest in quantum computing due to its role in developing fault-tolerant quantum algorithms with genuine computational adv…
Spin versus Magic: Lessons from Gluon and Graviton Scattering
John Gargalionis, Nathan Moynihan, Sokratis Trifinopoulos +3
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 myste…
Emergent symmetry in a two-Higgs-doublet model from quantum information and nonstabiliserness
Giorgio Busoni, John Gargalionis, Ewan N. V. Wallace +1
Studies of scattering processes in scalar models with two Higgs doublets have recently hinted at a connection between the absence of flavour-space entanglement in scatte…
