Quantum correlations and Wigner negativity are two important signatures of nonclassicality in continuous-variable quantum systems. In this work, we investigate how both intertwined the context conditional generation negativity. It was previously shown that when Alice Bob share a Gaussian state, can perform some measurement on his system to create Alice's side if only there is steering from Bob....
There are no known failures of Bounded Negativity in characteristic 0. In the light recent work showing Conjecture fails positive characteristics for rational surfaces, we propose new free conjectures as a replacement. We also develop bounds on numerical curves constraining their negativity. For example, show that $H$-constant curve $C$ with at most $9$ singular points satisfies $H(C)>-2$ regar...
Bell's theorem shows that no local hidden-variable model can explain the measurement statistics of a quantum system shared between two parties, thus ruling out classical (local) understanding nature. In this paper we demonstrate by relaxing positivity restriction in probability distribution it is possible to derive quasiprobabilistic Bell inequalities whose sharp upper bound written terms negat...
