Continuous variable quantum information: Gaussian states and beyond

G Adesso, S Ragy, AR Lee - Open Systems & Information Dynamics, 2014 - World Scientific
The study of Gaussian states has arisen to a privileged position in continuous variable
quantum information in recent years. This is due to vehemently pursued experimental …

Secure continuous variable teleportation and Einstein-Podolsky-Rosen steering

Q He, L Rosales-Zárate, G Adesso, MD Reid - Physical Review Letters, 2015 - APS

continuous variable teleportation to include quantum teleamplification protocols that allow …

Multipartite Gaussian steering: Monogamy constraints and quantum cryptography applications

Y **ang, I Kogias, G Adesso, Q He - Physical Review A, 2017 - APS
We derive laws for the distribution of quantum steering among different parties in multipartite
Gaussian states under Gaussian measurements. We prove that a monogamy relation akin to …

Measuring Gaussian quantum information and correlations using the Rényi entropy of order 2

G Adesso, D Girolami, A Serafini - Physical review letters, 2012 - APS
We demonstrate that the Rényi-2 entropy provides a natural measure of information for any
multimode Gaussian state of quantum harmonic systems, operationally linked to the phase …

Multipartite entanglement

M Walter, D Gross, J Eisert - Quantum Information: From …, 2016 - Wiley Online Library
