Statistical speech models and a probabilistic technique called Gaussian mixture modelling are then used to identify each phoneme, before reconstructing the original word.
The team says Jiuzhang's quantum computing system can implement large-scale " Gaussian boson sampling" 100 trillion times faster than the world's fastest existing supercomputer.
Their study used a classical simulation algorithm called Gaussian boson sampling to provide a highly efficient way of demonstrating such speedup in solving some well-defined tasks.
