ESA, EU, AIT, QKD, QUARTZ

The Austrian Institute of Technology joins the European Space Agency and global satellite operator SES in a venture to secure communications. Using quantum key distribution techniques, the goal is to enable quantum encryption key distribution via satellite. QKD via satellite overcomes the degradation of data over distance and, more importantly, provides a nearly unbreakable delivery of cryptographic keys.

Quantum Communication Communicating Atomic Time

Measuring time is a bit more involved when responsible for, say, Global Positioning Satellite (GPS), timing. A number of scientists are posing the idea of using quantum communication techniques to more accurately – and quickly – transfer atomic time between satellites and other timing systems. It is done through bypassing the classical computer conversions of numbers and data – in a simple sense.
