Low Noise Factory

Low Noise Factory (LNF) is an eight-person private company in Gothenburg, Sweden. It offers the lowest noise, highest performance microwave amplifiers (“LNA”) in the world. Our cryogenic models have become the de-facto standard in physics-related research throughout the world thanks to their unprecedented sensitivity. Our lowest noise model offers a noise figure of less than 0.03 dB (2 K). LNF provides its customers with state-of-the-art amplifiers for radio astronomy, physics research and telecom applications. LNF was founded in 2005 as a spin-off from Chalmers University of Technology. LNF’s amplifiers are built on the HEMT transistor technology developed at Chalmers over the past three decades.

Main tasks in the project

Within the OpenSuperQ project, LNF will tailor its products to meet the demands of the scaled-up qubit readout of tomorrow, targeting 100-qubit size systems. This includes size reduction, simplified assembly procedures and reduced power consumption.
