Improved GKP magic states from error-corrected non-Gaussian quantum states
Sharon David, Jack Davis, Ulysse Chabaud +1
Gate teleportation, together with magic state distillation, is a promising route towards fault-tolerant, universal computation. In the context of bosonic quantum computation, Barag…

Basis-independent stabilizerness and maximally noisy magic states
Michael Zurel, Jack Davis
Absolutely stabilizer states are those that remain convex mixtures of stabilizer states after conjugation by any unitary. Here we give a characterization of such states for multipl…

Extreme non-negative Wigner functions
Zacharie Van Herstraeten, Jack Davis, Nuno C. Dias +3
Providing an operational characterization of the Wigner-positive states (WPS), i.e., the set of quantum states with non-negative Wigner function, is a longstanding open problem. Fo…
