Our Mission

Intermodulation Products AB is dedicated to the research and development of measurement and analysis techniques for nonlinear physics and quantum technology. Our goal is to unlock the power of highly-parallel, real-time digital signal processing and low-latency feedback, for academic and industrial research and development. Our firmware unleashes the full power of field programmable gate arrays (FPGA) through simple Python programming. Our hardware is of the highest quality and designed for diverse laboratory applications. With our lock-in and software, you can transform a standard AFM into a state-of-the-art surface-analysis instrument. Our high-frequency pulse sequencer brings new possibilities to the measurement and control of quantum systems. Consult with us on your measurement problems and analysis needs.

CEO
Dr. Erik A. Tholén received his PhD from KTH in 2009. His work on parametric amplification in nonlinear superconducting resonant circuits lead to the development of Intermodulation AFM. His postdoctoral work centered on the development of the first Intermodulation Lock-in Analyzer. Erik co-founded Intermodulation Products and was the CEO from inception in 2010 to 2021. He specializes in hardware and software development.
Erik Tholén
CFO
Dr. Riccardo Borgani has two Master degrees, one from Politecnico di Milano and one from KTH. He received his PhD from KTH in 2018. His thesis developed Intermodulation Electrostatic Force Microscopy (ImEFM), as well as a fast, low-noise method to reconstruct nonlinear current-voltage characteristics for conducting AFM and STM (ImCFM). He went on to perform postdoctoral work at KTH working on fast readout of superconducting qubits. Riccardo joined Intermodulation Products full-time in 2022 after having been on the board and scientific advisory board for several years.
