Imec, a world-leading research and innovation hub in nanoelectronics and digital technologies, today announced the demonstration of high quality 300 mm-Si-based quantum dot spin qubit processing with devices resulting in a statistically relevant, average charge noise of 0.6µeV/√ Hz at 1 Hz. In view of noise performance, the values obtained are the lowest charge noise values achieved on a 300 mm fab-compatible platform.
Such low noise values enable high-fidelity qubit control, as reducing the noise is critical for maintaining quantum coherence and high fidelity control. By demonstrating those values, repeatedly and reproducibly, on a 300 mm Si MOS quantum dot process, this work makes large-scale quantum computers based on Si quantum dots a realistic possibility.
