Bluefors Oy is a company that specialises in cryogen-free dilution refrigerator systems, with a strong focus on the quantum computing and information community. Bluefors offers a wide range of standard systems with options that include wiring and superconducting magnets. In addition, our systems can be customised to meet the requirements of each individual customer.
In the OpenSuperQ project Bluefors will focus on the integration of a few key components in a modular and high density control and read-out solution for a dilution refrigerator (Bluefors XLD400 system).
The key task for Bluefors is to establish a design rule for the wiring and components that would be part of the integration into the dilution refrigerator. The company has long experience in implementing wiring solutions and integration of RF components into their cryogenic systems and sees it as a natural role to participate and implement a prototype of this high-density and modular solution.
Works at Bluefors as R&D Specialist in projects related to cryogenic sensors, electronics and software. He holds a Doctor of Science (Technology) degree from Helsinki University of Technology (now Aalto University). During his thesis work at Low Temperature Laboratory at Helsinki University of Technology his working areas were among others, setup of high-frequency cryogenic system for RF-SET measurements, cryogenic high-frequency amplifier design, and carbon nanotube sample processing and experiments. After his thesis, he worked around six years at VTI Technologies (now Murata) with MEMS element design and with MEMS component design for making concepts for combinations of MEMS elements, ASICs and packaging. Since 2010 he worked five years at Aivon Oy as Technical Director. Work consisted of i.e. design of electronics (embedded, digital, analog); design, mask drawing, packaging, measurement and simulation of CBT sensors.
is the head of the R&D environment at Bluefors. He holds a Ph. D. degree from Chalmers University of Technology, Sweden, 2005, on his work on the Josephson junction based quantum bit, the Cooper pair box in the team of Prof. Per Delsing. He continued as post-doc in at Low Temperature Laboratory, Helsinki University of Technology (2005-2008), now Aalto University, with work on Josephson tunnel junction qubit coupled to an electromagnetic resonant circuit. After his post-doc, he started his work at VTT Technical Research Centre of Finland as a research scientist (2008-2011) and continued as senior research scientist between 2011-2015 in the field of superconducting tunnel junction devices. He has contributed to research projects related to e.g. Josephson tunnel junction qubits, Superconductor-Semiconductor micro-coolers, Coulomb Blockade Thermometry and Graphene biosensors. He joined Bluefors in 2015 and was from the beginning involved in the R&D efforts as a Principal Scientist and is now leading the R&D efforts at BlueFors (since 2017).
is R&D Specialist at Bluefors. His work consists of cryogenic/mechanical designing and testing of new products. He holds a Doctor of Science (Technology) degree from Aalto University, Finland, 2015. His thesis work at the Low Temperature Laboratory at Aalto University covers experimental, theoretical and numerical studies on quantum fluids and solids at sub-milliKelvin temperatures. His thesis is one of the three awarded dissertations for physics at Aalto University in 2015. After thesis he joined Bluefors where he develops scientific instruments for low temperatures.
