About
Low Noise Factory (LNF) is a Swedish manufacturer of cryogenic low-noise amplifiers, components essential to quantum computing readout systems. Founded in 2004 in Gothenburg, LNF supplies cryogenic HEMT amplifiers for the 4K stage and traveling wave parametric amplifiers (TWPA) to quantum computing labs and companies worldwide, including IBM, Google, Rigetti, and academic research groups. Its amplifiers are critical for qubit state readout in superconducting and spin-based quantum processors. LNF was acquired by Infinitum Electric in 2024, a move that brought quantum-compatible low-noise electronics into quantum hardware supply chains.
