报告人简介:

Professor Neil Corzo received his PhD degree   from CINVESTAV-México in 2012. During his PhD, he did a 4-year-long research   stay at the Laser Cooling and Trapping Group at NIST (Maryland, USA). He did   two postdoctoral research stays, the first one at Northwestern University   (Illinois, USA), and the second one at the Laboratoire Kastler Brossel   (Paris, France). For the latter, he was awarded a Marie Curie Individual   Fellowship from the European Commission (2014-2016). Currently, he is a   Professor CINVESTAV-México.


报告内容:

Reversible light-matter interfaces are crucial   elements in quantum optics and quantum information networks. In particular,   the coupling of nanophotonic devices and cold neutral atoms appears as a   promising pathway to obtain not only better scalability and figures of merit than in free-space implementations, but also new paradigms for atom–photon  interactions. To this end, dielectric waveguides offer a promising platform   for such integration because they enable tight transverse confinement of the   propagating light, strong photon–atom coupling in single-pass configurations   and potentially long-range atom–atom interactions mediated by the guided   photons. However, the preparation of non-classical quantum states in such   atom–waveguide interfaces has not yet been realized.

In this talk, I will present the first   experimental realization of the coupling between a single collective atomic   excitation and a nanoscale waveguide. The stored collective entangled state can be efficiently read out with an external laser pulse, leading to   on-demand emission of a single photon into the guided mode.

This result demonstrates a capability that is   essential for the emerging field of waveguide quantum electrodynamics, with   applications to quantum networking, quantum nonlinear optics and quantum many-body physics.
