A contextual advantage for conclusive exclusion: repurposing the Pusey-Barrett-Rudolph construction
Yìlè Yīng, David Schmid, Robert W. Spekkens
The task of conclusive exclusion for a set of quantum states is to find a measurement such that for each state in the set, there is an outcome that allows one to conclude with cert…
Entanglement certification using noncontextuality inequalities
Yujie Zhang, Jonah Spodek, David Schmid +5
By combining the assumptions of Bell locality with those of generalized noncontextuality, we define classes of noncontextuality inequalities for correlations arising in a bipartite…
On whether quantum theory needs complex numbers: the foil theories perspective
Yìlè Yīng, Maria Ciudad Alañón, Daniel Centeno +5
Recent work by Renou et al. (2021) has led to some controversy concerning the question of whether quantum theory requires complex numbers for its formulation. We promote the view t…
Experimental Test of the Principle of Tomographic Locality
Tristan S. Lismer, Kaleb B. Felefele, Robert W. Spekkens +1
The principle of tomographic locality states that the operational state of a multipartite system can be fully characterized by the statistics obtained from measurements that are lo…
Reassessing the boundary between classical and nonclassical for individual quantum processes
Yujie Zhang, David Schmid, Yìlè Yīng +1
There is a received wisdom about where to draw the boundary between classical and nonclassical for various types of quantum processes. For multipartite states, it is the divide bet…
Fully quantum inflation: quantum marginal problem constraints in the service of causal inference
Isaac D. Smith, Elie Wolfe, Robert W. Spekkens
Consider the problem of deciding, for a particular multipartite quantum state, whether or not it is realizable in a quantum network with a particular causal structure. This is a fu…
