Secret key exchange in ultralong lasers by radiofrequency spectrum coding

HIGHLIGHTS

• who: Alessandro Tonello and collaborators from the (UNIVERSITY) have published the Article: Secret key exchange in ultralong lasers by radiofrequency spectrum coding, in the Journal: (JOURNAL)
• what: Although in this work, the authors consider fiber laser cavities of a ring type using erbium-doped fibers (EDFs), the results can be extended to different laser architectures, which may also include freespace propagation sections provided that the overall gain exceeds the cavity losses. The authors propose what is, to the extent of the knowledge , a completely new way of exchanging a secret key over an UFL link . . .
