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…

Revealing hidden physical nonclassicality with nonnegative polynomials
Ties-A. Ohst, Benjamin Yadin, Birte Ostermann +3
Understanding quantum phenomena which go beyond classical concepts is a focus of modern quantum physics. Here, we show how the theory of nonnegative polynomials emerging around Hil…
