Researchers from the University of Ottawa, in collaboration with Ben-Gurion University of the Negev and Bar-Ilan University scientists, have been able to create optical framed knots in the laboratory that could potentially be applied in modern technologies.

Their work opens the door to new methods of distributing secret cryptographic keys – used to encrypt and decrypt data, ensure secure communication and protect private information.

“This is fundamentally important, in particular from a topology-focused perspective, since framed knots provide a platform for topological quantum computations,” explained senior author, Professor Ebrahim Karimi, Canada Research Chair in Structured Light at the University of Ottawa.
According to the researchers, structured light beams are being widely exploited for encoding and distributing information.
“For the first time, these complicated 3D structures have been exploited to develop new methods for the distribution of secret cryptographic keys. [...]”

The applications
“Current technologies give us the possibility to manipulate, with high accuracy, the different features characterizing a light beam, such as intensity, phase, wavelength and polarization,” said Larocque.

“Our work opens the way to the use of more complex topological structures hidden in the propagation of a laser beam for distributing secret cryptographic keys.”
