The new frontier in quantum computing

… that is not just that of the laboratory but that of the real world (…) It is becoming possible to industrialise quantum technologies.

The challenge is to scale up and make these technologies scalable, which means reducing costs, mastering the technologies and hybridising them with conventional technologies (…).

This is an exciting time, with quantum systems beginning to operate with ten or twenty particles: quantum networks can be deployed over several hundred kilometres (…) Today, prototype quantum computers are beginning to rival conventional computers. We call this the computational advantage.

… and quantum cryptography to develop new protocols. By combining these two approaches, it is possible to do much more with quantum cryptography and gain a major security advantage over classical cryptography.

 

… on quantum communications began in March 2023. More than 40 European players are involved, including IP Paris and Télécom Paris, via the LTCI laboratory, where we are working on combining quantum technologies with digital technologies.
