Bound entanglement in symmetric random induced states
Jonathan Louvet, François Damanet, Thierry Bastin
Bound entanglement, a weak -- yet resourceful -- form of quantum entanglement, remains notoriously hard to detect and construct. We address this in this paper by leveraging symmetr…

The role of non-Markovian dissipation in quantum phase transitions: tricriticality, spin squeezing, and directional symmetry breaking
Baptiste Debecker, Lukas Pausch, Jonathan Louvet +3
Understanding how to control phase transitions in quantum systems is at the forefront of research for the development of new quantum materials and technologies. Here, we study how…

Nonequivalence between absolute separability and positive partial transposition in the symmetric subspace
Jonathan Louvet, Eduardo Serrano-Ensástiga, Thierry Bastin +1
The equivalence between absolutely separable states and absolutely positive partial transposed (PPT) states in general remains an open problem in quantum entanglement theory. In th…
