Quantum Communication Laboratory

The quantum communication laboratory contains 3 large ultra-stable and vibration isolated optical benches in a temperature controlled dust proof room. The laboratory contain many state of the art laser sources, including two frequency doubled Innolight Nd:YAG lasers producing beams at 1064nm and 532nm, one ultra-stable Innolight Nd:YAG laser at 1064 nm, one Toptica tunable diode laser producing light from the visible spectrum to the near infrared as well as a NP Photonics fibre laser source at 1550nm. These sources are used to pump optical parametric amplifiers of various geometries to produce non-classical states of light such as squeezed states and entangled states. To test quantum communication protocols, we have access to in-ground dark fibre loops from the Australian Capital Territory ICON network that are deployed in and around the National Parliamentary Triangle of Canberra. The laboratory hosts the ANU Quantum Random Number Generator Server (http://qrng.anu.edu.au) it is the only public server that measures vacuum fluctuations to generate random numbers on the World Wide Web.
