In a recent study, published
in Nature, ICFO researchers Nicolas Maring, Pau Farrera, Dr. Kutlu Kutluer, Dr.
Margherita Mazzera, and Dr. Georg Heinze led by ICREA Prof. Hugues de
Riedmatten, have achieved an elementary "hybrid" quantum network link
and demonstrated for the first time photonic quantum communication between two
very distinct quantum nodes placed in different laboratories, using a single
photon as information carrier.
The results of the study have
shown that two very different quantum systems can be connected and can
communicate by means of a single photon. As ICREA Prof at ICFO Hugues de
Riedmatten comments, "being able to connect quantum nodes with very
different functionalities and capabilities and transmitting quantum bits by means
of single photons between them represents an important milestone in the
development of hybrid quantum networks." The ability to perform back- and
forth-conversion of photonic qubits at the telecom C-band wavelength shows that
these systems would be completely compatible with the current telecom networks.
