A converter for quantum devices and future communications

Researchers at the Kastler Brossel Laboratory (LKB) have succeeded in building the first converter to make two types of quantum information coding communicate. This first could enable the interconnectivity of future networks. Quantum information covers both the field of quantum communications, which allows a secure exchange of information as well as quantum computing. This makes it possible to solve problems that are currently unsolvable in reasonable amount of time. In the race for quantum computing, many platforms are currently being developed, based on different quantum systems, such as photons, neutral atoms, ions, superconductors and semiconductors. For all these systems, several types of coding exist, and their choice depends on the specific applications and the available resources. Heterogeneity is therefore an urgent issue because there is currently no standardization of quantum telecommunications.
