Multipartite entanglement detection via projective tensor norms
Maria Anastasia Jivulescu, Cécilia Lancien, Ion Nechita
We introduce and study a class of entanglement criteria based on the idea of applying local contractions to an input multipartite state, and then computing the projective tensor no…
Weak approximate unitary designs and applications to quantum encryption
Cécilia Lancien, Christian Majenz
Unitary -designs are the bread and butter of quantum information theory and beyond. An important issue in practice is that of efficiently constructing good approximations of suc…
High-Dimensional Entanglement in States with Positive Partial Transposition
Marcus Huber, Ludovico Lami, Cécilia Lancien +1
Genuine high-dimensional entanglement, i.e. the property of having a high Schmidt number, constitutes a resource in quantum communication, overcoming limitations of low-dimensional…
de Finetti reductions for partially exchangeable probability distributions
Ivan Bardet, Cécilia Lancien, Ion Nechita
We introduce a general framework for de Finetti reduction results, applicable to various notions of partially exchangeable probability distributions. Explicit statements are derive…
