Gaussian entanglement revisited
Ludovico Lami, Alessio Serafini, Gerardo Adesso
We present a novel approach to the separability problem for Gaussian quantum states of bosonic continuous variable systems. We derive a simplified necessary and sufficient separabi…
Genuine-multipartite entanglement criteria based on positive maps
Fabien Clivaz, Marcus Huber, Ludovico Lami +1
Positive maps applied to a subsystem of a bipartite quantum state constitute a central tool in characterising entanglement. In the multipartite case, however, the direct applicatio…
Conditional and unconditional Gaussian quantum dynamics
Marco G. Genoni, Ludovico Lami, Alessio Serafini
This article focuses on the general theory of open quantum systems in the Gaussian regime and explores a number of diverse ramifications and consequences of the theory. We shall fi…
Schur complement inequalities for covariance matrices and monogamy of quantum correlations
Ludovico Lami, Christoph Hirche, Gerardo Adesso +1
We derive fundamental constraints for the Schur complement of positive matrices, which provide an operator strengthening to recently established information inequalities for quantu…
Bipartite depolarizing channels
Ludovico Lami, Marcus Huber
We introduce a 3-parameter class of maps acting on a bipartite system that are a natural generalisation of the depolarizing channel (and include it as a special case). Then, we fin…
