This breakthrough was done as part of our research project "CryptQ" led by DTU Physics, in which Innovation Fund Denmark has invested DKK 22.5 million. The purpose is to secure Denmark a position in the world market with a cost-effective technology for quantum communication. Our role as work package leader is to develop power-efficient lasers with extreme stability.
