Error exponent of activated non-signaling assisted classical-quantum channel coding
Aadil Oufkir, Marco Tomamichel, Mario Berta
We provide a tight asymptotic characterization of the error exponent for classical-quantum channel coding assisted by activated non-signaling correlations. Namely, we find that the…
Continuity of entropies via integral representations
Mario Berta, Ludovico Lami, Marco Tomamichel
We show that Frenkel's integral representation of the quantum relative entropy provides a natural framework to derive continuity bounds for quantum information measures. Our main g…
Asymptotic quantification of entanglement with a single copy
Ludovico Lami, Mario Berta, Bartosz Regula
Despite the central importance of quantum entanglement in quantum technologies, the understanding of the optimal ways to exploit it is still beyond our reach, and even measuring en…
