Macroscopic quantum coherence and entanglement in mechanical systems
Benjamin Yadin, Matteo Fadel
The notion of a macroscopic quantum state must be pinned down in order to assess how well experiments probe the large-scale limits of quantum mechanics. However, the issue of quant…

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…
