Researchers at the Universitat Politècnica de València (UPV) and the Universitat Miguel Hernández d'Elx (UMH) have developed a model that provides the basis for the application of commercial photonic components to the field of quantum computers and quantum communications.

The research has been published in the journal Laser and Photonics Reviews.

This is the first model published anywhere in the world that describes the full operation in quantum regime of integrated optical modulators, which are devices used to modulate light with information. Such devices make it possible to achieve speeds of around 100 Gb/s.

José Capmany, who is the director of the Universitat Politècnica de València's ITEAM Institute and one of the authors of this work, explains that these components, which are nowadays available commercially and used in broadband telecommunications, may be applied in the future to the production of logical systems and quantum computers by exploiting the properties unveiled in this study. These properties are related to the possibility of generating entangled states of light and being able to process them in a way similar to the logic gates in digital electronics.
