Researchers at LKB have found a way to translate one to another very distinct flavors of quantum information and thereby confirmed the possibility of interconnecting different quantum devices. In the race for quantum computing, many platforms are now being developed, relying on different quantum systems, such as photons, neutral atoms, ions, superconductors, and semiconductors. Tackling heterogeneity early on in the development of quantum networks can prevent from compatibility issues and allows for seamless integration and interconnectivity of different quantum systems in the future. This task calls to the use of a quantum encoding converter, a device that preserves the fragile encoded quantum information signal while changing the basis upon which it is written. Nonetheless this forced the team at LKB to take another route in order to create a converter: using quantum entanglement.
