Online seminar #19: Photon antibuching measurement using CdSe/ZnS quantum dots as single-emitters

Lidia Lozano Martín (ICCUB) Is it possible to develop an efficient solid-state emitter of single and entangled photons suitable for space to ground communications among other quantum applications? Present single-photon and entangled-photons emitters exhibit important challenges, limiting their use in quantum applications like secure communication based on quantum key distribution (QKD), quantum metrology and sensing.…

Online seminar #17: The device-independent scenario: quantum information processing based on Bell theorem

Antonio Acín (ICFO) Bell’s theorem proves the existence of quantum correlations, often known as Bell nonlocal, that cannot be described by classical theories, in which measurement outcomes are predetermined. In recent years, Bell nonlocal correlations have also acquired the status of information resource, as they are crucial for the construction of quantum information protocols in…

Online seminar #15: Quasiparticle focusing of Yu-Shiba-Rusinov states in gapped superconductors

Mateo Uldemonlins (Université Paris-Saclay, CNRS) A magnetic impurity on a conventional superconductor is one of the most simple pair-breaking defects that induces in-gap Yu-Shiba-Rusinov (YSR) bound states. Predicted soon after the publication of the BCS theory for superconductivity, they now enjoy a renewed wave of interest thanks to the advancements in atomic functionalization and local…

Online seminar #14: Magnetism in the 2D limit

Dorye L. Esteras (ICMol) The exfoliation of graphene down to the monolayer limit opened a new field of science based on infinitely thin materials. Encouraged by these findings, several efforts have been made in order to bring magnetism into the 2-dimensional (2D) limit. Despite the predictions of Mermin-Wagner theorem, these systems have magnetic order under…
