Local theories with parallel realities and the epistemic view of the quantum state
Alberto Montina, Stefan Wolf
Hidden-variable theories effectively solve the measurement problem. However, a serious issue of this route towards a realistic completion of quantum theory is raised by Bell's proo…
Quantum-foundational implications of information erasure upon measurement
Alberto Montina, Stefan Wolf
A projective measurement cannot decrease the von Neumann entropy if the outcome is ignored. However, under certain sound assumptions and using the quantum violation of Leggett-Garg…
Generalized Gleason theorem and finite amount of information for the context
A. Montina, S. Wolf
Quantum processes cannot be reduced, in a nontrivial way, to classical processes without specifying the context in the description of a measurement procedure. This requirement is i…
Can non-local correlations be discriminated in polynomial time?
Alberto Montina, Stefan Wolf
In view of the importance of quantum non-locality in cryptography, quantum computation and communication complexity, it is crucial to decide whether a given correlation exhibits no…
Optimal measurements for nonlocal correlations
Sacha Schwarz, Andre Stefanov, Stefan Wolf +1
A problem in quantum information theory is to find the experimental setup that maximizes the nonlocality of correlations with respect to some suitable measure such as the violation…
Simple algorithm for computing the communication complexity of quantum communication processes
A. Hansen, A. Montina, S. Wolf
A two-party quantum communication process with classical inputs and outcomes can be simulated by replacing the quantum channel with a classical one. The minimal amount of classical…
