Convex optimization on moment polytopes: Hadamard mirror descent and efficient algorithms for quantum functionals and other tensor parameters
Mahmut Levent Doğan, Keiya Sakabe, Michael Walter
Convex optimization on polytopes arises in many areas of science. When the polytope is given implicitly or has exponentially many vertices and facets, standard methods may not appl…
Strassen's support functionals coincide with the quantum functionals
Keiya Sakabe, Mahmut Levent Doğan, Michael Walter
Strassen's asymptotic spectrum offers a framework for analyzing the complexity of tensors. It has found applications in diverse areas, from computer science to additive combinatori…
Guess your neighbor's input: Quantum advantage in Feige's game
Simon Schmidt, Sigurd A. L. Storgaard, Michael Walter +1
In this article, we study a nonlocal game with two questions and three answers per player, which was first considered by Feige in 1991, and show that there is quantum advantage in…
Probing the single neurotransmitters with the WGM microcavity-hybridized plasmonic nanospiked antennas
Aneeth Kakkanattu Arunkumar, Ekaterina Zossimova, Michael Walter +3
Discerning the neurotransmitter dysregulation is a hallmark of neurological disorders and diseases, including Alzheimer's, Parkinson's, and multiple sclerosis. The concentration of…
