The conditional entropy power inequality for Gaussian quantum states (1304.7031v1)
Published 25 Apr 2013 in quant-ph
Abstract: We propose a generalization of the quantum entropy power inequality involving conditional entropies. For the special case of Gaussian states, we give a proof based on perturbation theory for symplectic spectra. We discuss some implications for entanglement-assisted classical communication over additive bosonic noise channels.
