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.

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.

Scientists at Linköping University have managed to simulate quantum computer properties in a classical computer. “Our results should be highly significant in determining how to build quantum computers”, says Professor Jan-Åke Larsson.
