With the help of a new experiment, researchers at LiU, have succeeded in confirming a ten-year-old theoretical study, which connects the complementarity principle with information theory.

Recently, a full-day seminar on AI and Security was held at Linköping University. The seminar was organized by SWECA in collaboration with Linköping University, the County Administrative Board of Östergötland, and The Swedish Police Authority.

So-called quantum encryption will ensure the security of sensitive information – but this new technology has to be tested outside the lab environment. LiU is therefore taking part in a project studying secure communication channels of the future.

Digital information exchange can be safer, cheaper and more environmentally friendly with the help of a new type of random number generator for encryption developed at LiU. The technology paves the way for a new type of quantum communication.

An optical circuit capable of ensuring the security of quantum cryptography. The idea that researchers Alvaro Alarcón and Guilherme B. Xavier had five years ago has now been tested and could pave the way for the future of secure communication.
