Characterising memory in quantum channel discrimination via constrained separability problems
Ties-A. Ohst, Shijun Zhang, Hai Chau Nguyen +2
Quantum memories are a crucial precondition in many protocols for processing quantum information. A fundamental problem that illustrates this statement is given by the task of chan…
The polarization hierarchy for polynomial optimization over convex bodies, with applications to nonnegative matrix rank
Martin Plávala, Laurens T. Ligthart, David Gross
We construct a convergent family of outer approximations for the problem of optimizing polynomial functions over convex bodies subject to polynomial constraints. This is achieved b…
No-broadcasting characterizes operational contextuality
Pauli Jokinen, Mirjam Weilenmann, Martin Plávala +3
Operational contextuality forms a rapidly developing subfield of quantum information theory. However, the characterization of the quantum mechanical entities that fuel the phenomen…
