Finnish quantum technology startup S-Transistors has secured €2.6 million in pre-seed funding to develop integrated circuits using superconducting transistors. The primary focus of this investment is to address control and signal-routing challenges in scaling cryogenic quantum computers. The round was spearheaded by Nordic early-stage investor Lifeline Ventures, with additional backing from a single angel investor.
S-Transistors, which traces its origins to VTT Technical Research Centre of Finland, is developing superconducting transistor technology that offers high-speed performance and ultra-low power consumption at cryogenic temperatures. While the technology holds potential across classical computing, AI, high-performance computing hardware, spacecraft electronics, and particle detectors, the company is currently concentrating on quantum computing.
Scaling superconducting quantum computers necessitates more efficient methods for controlling processors and transmitting signals. Currently, a substantial portion of control electronics operates at room temperature and connects to the quantum processor through multiple cables, which becomes increasingly intricate and power-hungry as the number of qubits rises.
By bringing these hardware components closer to the quantum processor, S-Transistors aims to enhance scalability. Conventional silicon transistors, however, encounter performance and power limitations when functioning at cryogenic temperatures. The company's superconducting transistors are already operational at wafer scale. According to the startup's co-founder and CEO, Dr. Heorhii Bohuslavskyi, integrating control and interface hardware closer to the quantum chip could pave the way for larger systems, provided the electronics can function efficiently at extremely low temperatures.
S-Transistors' inaugural product will be a superconducting-transistor-based multiplexer, intended to be integrated with existing cryogenic setups and support quantum device development and prototyping. The company intends to deliver this product to early customers and strategic partners during its first year of operation. The funding will be allocated towards developing cryogenic signal control and handling prototypes, establishing a cryogenic laboratory, setting up a pilot manufacturing line for its integrated circuits, and expanding the team.
