To fully leverage the potential of quantum computing, error correction must be completed before errors occur. With enhanced connectivity between quantum bits, the redundancy and error rate requirements for achieving fault-tolerant quantum computing can be relatively reduced. Even so, the required redundancy will quickly push the number of quantum bits into the millions. Considering the … Read more
Among the four main hardware components in the perception layer of autonomous driving, cameras are undoubtedly the one with the highest certainty for future growth. With their high performance combined with low cost, cameras are indispensable hardware for achieving autonomous driving, whether using a pure vision solution or a multi-sensor fusion approach, and there is … Read more
Today is the last day of March, marking the conclusion of this series on imported junk.
