In the forthcoming era of quantum computing, revisions will be forced on secure communication. Modern public-key communication systems are vulnerable to attacks by quantum computers. Fortunately, there already exists quantum-safe encryption algorithms and quantum-based solutions.

The US National Institute of Standards and Technology has published the first draft of the post-quantum cryptography standard. In the EU quantum communication has been researched and developed in the EuroQCI initiative. In Finland, quantum safe communication has been studied and implemented in several research projects. We summarize the research projects and publications on quantum-safe communication in Finland and discuss future research activities.
