Espoo-based quantum technology startup S-Transistors has secured €2.6 million in pre-seed funding. The company aims to revolutionize the control of large-scale quantum computers by developing a novel superconducting transistor platform.

The capital raised will be used by S-Transistors to advance the development of its superconducting transistors, which are seen as crucial for addressing the scalability challenges in quantum computing. Traditional transistors are not suitable for efficiently controlling quantum bits (qubits), and the new technology proposes a solution.

The startup's technology combines superconductivity with the signal amplification capabilities of transistors. This is expected to enable precise and fast control of qubits without interference, a critical factor for progress in quantum computation. The company intends to integrate its hardware into future quantum computers.

S-Transistors was founded by researchers with expertise in superconducting electronics and quantum technology. The company's technology is based on research conducted at VTT Technical Research Centre of Finland. The goal is to create a standardized solution that accelerates the commercialization of quantum computers.
