In this talk, we shall present a series of inequalities for quantum symmetries such as Hausdorff-Young inequalities, Young's inequalities, uncertainty principles, sumset estimation and entropic inequa...
Fano type quantum inequalities in terms of $q$-entropies
Fano inequality Tsallis q-entropy relative q-entropy entanglement fidelity
2010/11/4
Generalizations of the quantum Fano inequality are considered. The notion of $q$-entropy exchange is introduced. This quantity is concave in each of its two arguments. For $q\geq0$, the inequality of ...
A short remark on negative energy densities and quantum inequalities
negative energy densities quantum inequalities
2010/4/7
In quantum field theory it is generally known that the energy density may be negative at a given point in spacetime. A number of papers have shown that there is a restriction on this energy density wh...
