Quantum Technologies for Long-Term Data Security

Quantum computing poses a major threat to the most commonly deployed public key cryptography algorithms, which are key building blocks of our information security infrastructure. With advances in the field of quantum computing, it becomes important to upgrade this infrastructure to use approaches with a resistant to this threat. One approach is to use quantum technologies, such as quantum key distribution and quantum random number generation, in combination with traditional cryptographic techniques in order to enhance their resilience. In this presentation, we will review the current state of the art of practical quantum key distribution and quantum random number generators and discuss current areas of research. We will also present examples of applications and use cases.

About the Speaker

Grégoire Ribordy studied physics at the Swiss Federal Institute of Technology in Lausanne, where he obtained his master in 1995 with a specialization in optics. Passionate about applications of science and technology, he then decided to join industry and had the opportunity to work in the R&D department of Nikon Corp. in Tokyo, Japan. During his 18 months stay in this country, Ribordy also learned to speak Japanese. Upon his return to Switzerland, Ribordy decided to go back to academia to obtain his PhD, but he was careful to select a research group with strong ties to applications and from which start-ups had already been spun off. He thus joined the Group of Applied Physics of University of Geneva and worked in the field of quantum cryptography under the guidance of Prof. Nicolas Gisin and Hugo Zbinden. After obtaining his PhD in 2000, he decided to start a company in October 2001– ID Quantique – to pursue the commercial opportunities of quantum technologies in the field of secure communications. The company was the first to bring products such as quantum random number generators and quantum cryptography to the market. In 2007 in a world premiere, ID Quantique’s quantum cryptography solution was used to secured communication between two datacenters in Geneva, Switzerland. ID Quantique currently has a staff of about 100 employees and is the world leader in the field of quantum-safe cryptography. In October 2016, Ribordy has been appointed to the High-Level Steering Group set up by the European Commission to provide advice on its Quantum technologies strategy. In October 2017, Ribordy, along with other ID Quantique co-founders Profs. Nicolas Gisin and Hugo Zbinden, received the Innovation Medal of the University of Geneva. More recently, in September 2018, he has been selected as one of the 100 Digital Shapers (people who lead digitalization of the country) in Switzerland. Ribordy has co-authored more than 25 scientific papers and is listed as an inventor on more than 10 patents. Ribordy is also the recipient of several awards for technology entrepreneurship such as the 2001 New Entrepreneurs in Technology and Science Prize or the 2002 de Vigier Award for Young Swiss Entrepreneurs.
