Stabilizer Entropy of Subspaces
Simone Cepollaro, Gianluca Cuffaro, Matthew B. Weiss +3
We consider the costs and benefits of embedding the states of one quantum system within those of another. Such embeddings are ubiquitous, e.g., in error correcting codes and in sym…

Non-stabilizerness and violations of CHSH inequalities
Stefano Cusumano, Lorenzo Campos Venuti, Simone Cepollaro +7
We study quantitatively the interplay between entanglement and non-stabilizer resources in violating the CHSH inequalities. We show that, while non-stabilizer resources are necessa…
