Stawell underground lab hosts quantum research
Researchers have travelled deep underground to examine how cosmic rays influence the phase noise and performance of timekeeping technology.
In a partnership between the ARC Centre of Excellence for Engineered Quantum Systems and Quantic Wenzel, a business that develops frequency control and timing solutions, scientists are testing quartz crystal oscillators in the Stawell Underground Physics (SUPL).
It is the first fundamental scientific experiment to be conducted in SUPL, which is located 1km underground in Stawell Gold Mines.
The underground location, and equipment that will also be used for the CELLAR equipment in SUPL, enables the oscillators to be tested in a way that has not been possible before, potentially revealing new insights into oscillator phase noise limitations.
Centre members Maxim Goryachev, Ben McAllister and William Campbell are undertaking the research in SUPL and have taken preliminary measurements onsite.
Dr Campbell travelled into SUPL for the first time to work on the project.
“The experience was unique and exciting and it was made very easy by the SUPL staff,” he said.
Dr Goryachev said the project offered benefits for both science and industry.
“This partnership will bring unprecedented clarity to the field, expanding our understanding of fundamental physics while advancing innovation in quantum technologies and high-tech industries.”
By testing quartz-based oscillators alongside Quantic Wenzel, EQUS is bridging academic and industry expertise to advance commercial timekeeping technology and explore new horizons in fundamental physics.
