VTT Info’s S-Transistors Grabs €2.6M To Build Quantum Computer Control Chips

S-Transistors, a Finnish startup originating from VTT Technical Research Centre of Finland, secured €2.6 million in pre-seed funding to develop superconducting transistors for controlling quantum computers. The company is building quantum motherboards designed to provide energy- and cost-efficient orchestration of cryogenic quantum computers at scale, addressing a critical limitation in current technology. “Today’s efforts in scaling cryogenic quantum computers have delivered tremendous progress,” says Dr. Heorhii Bohuslavskyi, Co-founder and CEO of S-Transistors.

“However, further scaling is approaching a hard wall, as it still relies on power-hungry room-temperature electronics and separate wiring for each quantum bit (qubit) – both used to operate the quantum computer and link it to the outside world. The clearest path forward, for superconducting quantum computers in particular, is to bring the classical control and interface hardware down into the cryostat, right next to the quantum chip kept cold to protect its fragile quantum states.” These novel devices combine transistor computational power with the ultra-low power dissipation of superconductors.
