Colloquium
Quantum Science and Technology

Resumen

The discovery of Quantum Physics gave rise to one of the most important scientific and technological revolutions experienced by mankind. It triggered, for instance, the discovery of lasers, semiconductors, or nuclear power. In the last few years we are experiencing a second "Quantum Revolution", where the most exotic features of Quantum Physics can not only be confirmed, but also have major technological consequences. In particular, new cryptographic and computational opportunities are emerging, which will be impossible to reach with any other technology. Nowadays, there exists an extensive international effort to build quantum computers, cryptographic systems, as well as other devices. In this talk I will explain the basics of all those devices, their potential applications, as well as the status of that international effort and its prospects of giving rise to powerful technologies.
