Information Coding (ICG)

Quantum technology and information security

 InformationskodningPhoto credit: Thor BalkhedThe Division of Information Coding performs research and education within quantum technology, currently concentrated into quantum computing and quantum cryptography. The division also holds undergraduate courses in more general information technology, cryptography, and image and video coding. The group is led by Professor Jan-Åke Larsson.

Research activities

Our research lab offers quantum-optical equipment that we use to conduct research into next-generation secure communication systems, also known as “quantum cryptography”, in which security is guaranteed by the quantum properties of light.

Our theoretical research concerns quantum computers and quantum algorithms, how they work, and why quantum computers have larger computational power than standard computers.
