The Frequency and Quantum Metrology Laboratory (FQM) research group has two laboratories associated with the Centre.
The first led by CI Michael Tobar, are world leaders in precision measurement, low temperature physics and hybrid quantum systems. They have a long history of research in precision measurement, materials characterisation, electron spin and spin wave resonance spectroscopy, novel ultra-high Q-factor resonators and sensors, and the development of frequency stable, low phase noise instruments with world-class precision and performance. One such device, the Cryogenic Sapphire Oscillator, is now found in metrological laboratories around the globe, and has allowed atomic fountain clock technology to reach its ultimate performance, as well as being used in some of the most precise tests of fundamental physics ever performed. The group’s research has also led to a number of practical technologies that have been successfully patented and commercialised.
The lab offers access to:
The second led by CI John McFerran, are experts in atomic clock technology, including laser frequency control, atomic control with lasers and magnetic fields (e.g. laser cooling), electronic designs, optical designs, optoelectronic control systems and optical frequency synthesis.
The lab offers:
The FQM laboratories also maintain equipment for the comparison of clocks with NMI in Sydney over GPS Carrier Phase and Two-way Satellite technology.
