Datacommunication
Datacommunication applications
With the advent of quantum computing, data communication is taking a new turn. Fiber optics is more than ever at the heart of all the attention, whether for quantum communication or quantum metrology applications.
Quantum Communication
Photonics plays a central role in the development of quantum information technologies. Quantum key distribution systems for cryptography are already on the market and, thanks to their speed and robustness to decoherence, photons are at the heart of many advances towards large-scale secure networks, metrological systems, and quantum processors.
Case Studies
Quantum Metrology
Quantum photonics is now entering a new field of application, related to metrology and quantum sensors. In particular, it is used for spectroscopy to characterize materials. Special new generation optical fibers allow to work at cryogenic temperatures, which are essential for the proper functioning of single-photon sources (semiconductor quantum emitters).
