Contextuality and Wigner negativity are equivalent for continuous-variable quantum measurements
Robert I. Booth, Ulysse Chabaud, Pierre-Emmanuel Emeriau
Quantum computers will provide considerable speedups with respect to their classical counterparts. However, the identification of the innately quantum features that enable these sp…

Witnessing Wigner Negativity
Ulysse Chabaud, Pierre-Emmanuel Emeriau, Frédéric Grosshans
Negativity of the Wigner function is arguably one of the most striking non-classical features of quantum states. Beyond its fundamental relevance, it is also a necessary resource f…
