Genuine Global Kochen-Specker Contextuality as Classical Coordination Cost
Ming Yang
We formulate classical simulation of quantum correlations as coordination across a spacetime separator. All past-dependent information capable of influencing the future must cross…
Global Kochen-Specker Contextuality Without Local Contextuality and Generalized Bell Nonlocality
Ming Yang
A set of quantum data can look classical in every local test and still fail to admit a single classical explanation of the whole composite system. We formulate this failure as glob…
Ontic Dynamical Locality Reduces to Bell Locality
Ming Yang
Bell inequalities exclude a broad class of local hidden-variable explanations of quantum correlations. A recurring objection is that the usual Bell form is static, whereas real mea…
Extracting conserved operators from a projected entangled pair state
Wen-Tao Xu, Miguel FrÃas Pérez, Mingru Yang
Given a tensor network state, how can we determine conserved operators (including Hamiltonians) for which the state is an eigenstate? We answer this question by presenting a method…
