Optimal quantum teleportation protocols for fixed average fidelity
Fabricio Toscano, Diego G. Bussandri, Gustavo M. Bosyk +2
We demonstrate that among all quantum teleportation protocols giving rise to the same average fidelity, those with aligned Bloch vectors between input and output states exhibit the…
Rényi-Holevo inequality from --Rényi relative entropies
Diego G. Bussandri, Grzegorz Rajchel-Mieldzioć, Pedro W. Lamberti +1
We investigate bounds in the transmission of classical information through quantum systems. Our focus lies in the generalized Holevo theorem, which provides a single-letter Holevo-…
Transmission distance in the space of quantum channels
Diego G. Bussandri, Pedro W. Lamberti, Karol Życzkowski
We analyze two ways to obtain distinguishability measures between quantum maps by employing the square root of the quantum Jensen-Shannon divergence, which forms a true distance in…
