Two papers developed by researchers from the Center For Optics and Photonics were accepted at the 4th International Conference on Quantum Cryptography (QCrypt 2014). These works will be presented at the poster session by Gonzalo Carvacho, a member of the Optoelectronics Division and Esteban Sepulveda, a member of Optics and Quantum Information Division.
QCrypt‘s objective is to promote the latest advances in this area, which uses the fundamental quantum physics principles to achieve improvements in safety, one of the most promising fields for future quantum technology.
In this context, during the second day afternoon of QCrypt 2014, Gonzalo Carvacho presented the poster entitled Towards genuine energy-time entanglement in quantum cryptography installed telecom fibers. “At the conference in 2013 we presented some results and now we want to spread the latest data obtained in the Optronics laboratory, associated with interferences between photons to send a photon to the Observatory TIGO” Gonzalo said.
This work included the participation of Gabriel Saavedra, Alvaro Cuevas, Jaime Carine, Meunier Matthieu, Miguel Figueroa, Gustavo Lima, Guilherme Xavier and foreign researchers Paolo Mataloni, Adán Cabello, Jan-Ake Larsson.
Meanwhile, Esteban Sepúlveda displayed the poster Quantum key distribution Session with 16-dimensional photonic states, finding from the paper written by our Scientist Director Dr. Carlos Saavedra and researchers Guilherme Xavier, Gustavo Lima, Sebastian Etcheverry, Gustavo Cañas y Wallon Nogueira, work which was published in the Scientific Reports journal in 2013.
“In addition to presenting this work, I’m very interested in a presentation by Dr. Nicolas Brunner, because he works with the Bell inequalities, which are used to verify the theory of quantum mechanics nonlocality”, he said. Taking this opportunity, Esteban will also visit Nobel Prize of Physics, Dr. Serge Haroche laboratories, in Paris VI University, where Carla Hermann, researcher from our Center, is currently working.
