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.
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.
Niklas Wadefalk, Chief Executive Officer (CEO) at Low Noise Factory, received his B.Sc. degree in electrical engineering from Chalmers University of Technology, Göteborg, Sweden, in 1994. He worked as an RF engineer at California Institute of Technology from 2001 to 2005, where he specialized in cryogenic InP HEMTs. He co-founded Low Noise Factory in 2005, where he now works as CEO.
Dr Arsalan Pourkabirian, Process Engineer at Low Noise Factory, received his M.Sc. and Ph.D. degrees in 2009 and 2014, respectively, from Chalmers University of Technology, Göteborg, Sweden. During his Ph.D he studied noise sources in mesoscopic devices and quantum states of microwaves. From 2015 to 2017 he joined the microwave electronic laboratory at Chalmers University where he studied cryogenic low noise amplifier and from 2017 he is working as a process engineer at Low Noise Factory.
