Entanglement generation through particle detection in systems of identical fermions
(Academic Press Inc Elsevier Science, 2017-08)
We investigate the generation of entanglement in systems of identical fermions through a process involving particle detection, focusing on the implications that these kindsof processes have for the concept of entanglement ...
A discourse on entanglement and its detection in finite dimensions
(Universidade Federal de Minas GeraisUFMG, 2011-08-26)
We explore procedures to detect entanglement of unknown mixed states, which can be experimentally viable. The heart of the method is a hierarchy of semi-definite programs, which provides sufficient conditions to entanglement. ...
Closure of the entanglement gap at quantum criticality: The case of the quantum spherical model
(American Physical Society, 2020-12)
The study of entanglement spectra is a powerful tool to detect or elucidate universal behavior in quantum many-body systems. We investigate the scaling of the entanglement (or Schmidt) gap δξ , i.e., the lowest-laying gap ...
Genuine multipartite entanglement in quantum phase transitions

Superfluid-Insulator Transition unambiguously detected by entanglement in one-dimensional disordered superfluids
(Nature Publishing Group, 2019-10-25)
We use entanglement to track the superfluid-insulator transition (SIT) in disordered fermionic superfluids described by the one-dimensional Hubbard model. Entanglement is found to have remarkable signatures of the SIT ...
Photonic entanglement sources: high quality and high-dimensional implementations.
(Universidad de Concepción.Facultad de Ciencias Físicas y MatemáticasDepartamento de Física., 2020)
Entanglement is a physical phenomenon described by the quantum theory. When the system is
composed by two or more entangled particles, their quantum state must be understood as a whole, not as independent quantum states, ...
