AI can solve partial differential equations thousands of times faster than before, and partial differential equations play an important role in engineering and science. In a recent study, scientists from Johns Hopkins University in the United States have developed a new artificial intelligence (AI) model called "Differential Mapping Operator Learning" (DIMON), which can solve complex partial differential equations on personal computers, thousands of times faster than before, and is expected to "show its talents" in the fields of aerospace, automobiles and medicine.

According to a paper published in Nature magazine on the 10th, Google's latest generation of quantum chips has achieved a breakthrough in error correction capability, that is, the error is suppressed below a critical threshold. This quantum error correction function is considered as a necessary condition to realize the practical application of quantum computing in the future. After the performance of the chip is expanded, it may be able to promote the operation requirements of large-scale fault-tolerant quantum computing. (Science and Technology Daily)
