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…
Detecting quantum non-Gaussianity with a single quadrature
Clara Wassner, Jack Davis, Sacha Cerf +2
Full reconstruction of quantum states from measurement samples is often a prohibitively complex task, both in terms of the experimental setup and the scaling of the sample size wit…
Quantum recurrences and the arithmetic of Floquet dynamics
Amit Anand, Dinesh Valluri, Jack Davis +1
The Poincaré recurrence theorem shows that conservative systems in a bounded region of phase space eventually return arbitrarily close to their initial state after a finite amount…
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…
Grand Unification of All Discrete Wigner Functions on Phase Space
Lucky K. Antonopoulos, Dominic G. Lewis, Jack Davis +2
Wigner functions help visualise quantum states and dynamics while supporting quantitative analysis in quantum information. In the discrete setting, many inequivalent constructions…
