The squashed entanglement of the noiseless quantum Gaussian attenuator and amplifier
Giacomo De Palma
We determine the maximum squashed entanglement achievable between sender and receiver of the noiseless quantum Gaussian attenuators and amplifiers and we prove that it is achieved…

The Entropy Power Inequality with quantum conditioning
Giacomo De Palma
The conditional entropy power inequality is a fundamental inequality in information theory, stating that the conditional entropy of the sum of two conditionally independent vector-…

New lower bounds to the output entropy of multi-mode quantum Gaussian channels
Giacomo De Palma
We prove that quantum thermal Gaussian input states minimize the output entropy of the multi-mode quantum Gaussian attenuators and amplifiers that are entanglement breaking and of…
