Decoherence without the state: A causal quantum Darwinist approach
Nick Ormrod, Tein van der Lugt, Yìlè Yīng +1
The consistent histories formalism can be used to describe histories comprised of events across many systems, times, and places, plausibly rich enough to describe our experiences o…
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…
Quantum oracles give an advantage for identifying classical counterfactuals
Ciarán M. Gilligan-Lee, Yìlè Yīng, Jonathan Richens +1
We show that quantum oracles provide an advantage over classical oracles for answering classical counterfactual questions in causal models, or equivalently, for identifying unknown…
A structure theorem for complex-valued quasiprobability representations of physical theories
Rafael Wagner, Roberto D. Baldijão, Matthias Salzger +3
Quasiprobability representations are well-established tools in quantum information science, with applications ranging from the classical simulability of quantum computation to quan…
Copenhagenish interpretations of quantum mechanics
David Schmid, Yìlè Yīng, Matthew Leifer
We define a class of Copenhagenish interpretations encompassing modern interpretations that follow the Copenhagen spirit. These interpretations are characterized by four postulates…
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…
