Tight entropy bound based on p-quasinorms
Juan Pablo Lopez
In the present paper we prove a family of tight upper and lower bounds for the Shannon entropy and von Neumann entropy based on the p-norms. This allows us to have an entropy estim…

Quantum states as countable convex combination of pure states with bounded energy
Juan Pablo Lopez
We give response to the question: in infinite dimension states,given a state with energy bounded by E, we can write the state as a countable convex combination of pure states with…
