A Classical Architecture For Digital Quantum Computers
The First Scalable Real-time Decoding Firmware
Fast classical processing is essential for most quantum fault-tolerance architectures. We pioneered the slicing-window parallel decoding approach that provides fast classical processing for the surface code through parallelism. This scheme significantly accelerates classical processing by leveraging parallelism, effectively overcoming a major bottleneck in fault-tolerant quantum computing for the first time. Our work has garnered widespread recognition within the scientific community. It has been featured in presentations at leading institutions like MIT and Duke. Additionally, our team has been honored with an invitation to speak at the QEC23, a prominent conference on quantum error correction.
