The investigator Juan José García-Ripoll member of quitemad interviewed in the newspaper ” El País”

Technological giants like IBM, Microsoft, Intel or Google focus their efforts on leading the battle of quantum computing. This technology is destined to revolutionize computing in the future due to its extraordinary capacity for calculation. But it also puts current encryption systems at risk. “The mere existence of the quantum computer, no longer as a concept but as an experimental reality, means that we must abandon conventional cryptography techniques”, explains Juan José García Ripoll (Madrid, 1974), researcher at the Institute of Fundamental Physics of the Higher Council of Scientific Investigations.
This tool, “potentially, can decipher the keys we are transmitting on the Internet.” That is, someone could store all that information and in the future access it. For García Ripoll, “that our communications with the bank are intercepted now and decrypt in 10 years is not a problem”. But it is from the point of view of states, government organizations, defense or large companies. There are countries like China or the United States that invest a lot of money in this research. “It can be dangerous for a State to have a quantum computer, we do not know it and it is decrypting the keys of the whole world,” he says. Although he considers that this situation is “unlikely”, he points out that “it is a sufficiently important risk for Europe and other countries to decide to invest in the field”.Technological giants like IBM, Microsoft, Intel or Google focus their efforts on leading the battle of quantum computing.

The threat posed by quantum computing to today’s encryption systems will force the creation of new encryption algorithms capable of withstanding these quantum computers. The researcher explains that there are two possible routes. “One is to look for more difficult mathematical problems and to show that those problems can not be broken in a quantum computer. That seems quite difficult because demonstrating that something can not be done is even more difficult than demonstrating what can be done, “explains García Ripoll, who is part of the quantum information group of the Institute of Fundamental Physics and has been one of the speakers in Tomorrow. begins today, an event in which experts from diverse topics have reflected on the challenges of the near future.
Quantum cryptography “is a technological reality right now”. In Spain, Telefónica has investigated in this area: “It has shown that in principle it is a commercially viable solution. It is the first company to verify that it is possible to do cryptography through the commercial fiber optic network “. More recently, on June 13, Belgium, Germany, Italy, Luxembourg, Malta, the Netherlands and Spain signed a statement in which they agreed to explore together during the next year how to develop and deploy a quantum communication infrastructure across the Union European Union in the next ten years.
