Chinese researchers report that a small-scale quantum system can achieve performance comparable to expensive, large-scale AI computing centers, significantly reducing costs.

An AI computing centre capable of predicting weather patterns weeks in advance typically carries a price tag of US$100 million or more. Now, Chinese researchers say a small-scale quantum system can outperform such facilities at less than 1 per cent of the cost. The findings raise questions about the long-term economics of the global artificial intelligence infrastructure race. If compact quantum systems can deliver competitive performance in specific tasks, could today’s colossal data centres...
