We operate a source of quantum random numbers in our lab. The numbers are generated from the quantum vacuum fluctuations measured using balanced homodyne detection.

To access the random numbers you...

Normal, classical optical signals are carried by changing the amplitude of the light and the signal may be detected simply with a photodetector. In this case a piece of paper, or a computer hard-drive...

Light carries momentum. When light is reflected or absorbed, the change in momentum results into the exertion of a pressure on the incident surface, known as radiation pressure. An optical cavity can...

Modern telecommunications have revolutionised the way we communicate and quantum communications is the next evolution making us even more connected. First, quantum communication will provide a new sec...

The ANU quantum information group have been working on many varied projects. We use lasers to create continuous variable quantum states. We then use these states to do fun things. Some of the projects...
