Research

My research interests focus on the area of quantum information, and especially quantum cryptography.
I completed my Ph.D. at the Technion in the group of Prof. Tal Mor.

Presently, I am a postdoctoral fellow at the Institute of Photonic Sciences (ICFO) in Barcelona, in the group of Prof. Dr. Antonio Acín.
