The banking, financial, and defence sectors crucially depend on communication through channels that cannot be intercepted by unauthorized people. Today, different types of sensitive information are sent within and between companies. All of these users employ cryptography to keep their data secret. Today’s cryptographic protocols rely on RSA or so-called elliptical curves methods. Unfortunately, there is no guarantee that these methods will remain safe in the near future, especially having in mind the potential growth of the computation power. Fortunately, quantum mechanics makes it possible to solve the key transfer problem in a new and proven safe manner. Unlike RSA and similar methods, it is nature’s laws that guarantee the security of quantum cryptography. In this talk, I will introduce and review our research in quantum secure communication and also the worldwide effort in quantum technologies.
Mohamed Bourennane is a professor at Stockholm University. He has obtained his PhD from the Royal Institute of Technology, Stockholm. He was a researcher at Ludwig Maximilians University, Munich and Max Planck Institute for Quantum Optics, Garching, Germany. He has obtained the six years of senior research fellow from the Swedish Research Council (VR). Today, he has established very young and dynamic research group in quantum information and cryptography at Stockholm University. He has initiated, managed, and led projects financed from, VR, Knut and Alice Wallenberg Foundation (KAW), Stiftelsen Olle Engkvist, Carl Tryggers Foundation, and the Swedish Agency for Exchange Programs (STINT), Defence Material Administration (FMV), ABB, EU, and Polish National Foundation. He is an elected member of the Royal Swedish Academy of Sciences.
