Researchers from China, at the University of Science and Technology of China, developed the quantum computer Jiuzhang, which completed a task in just 4 minutes that would take 2.6 billion years for a classical supercomputer to finish.
Using the advanced technique of Gaussian boson sampling with photons in an optical circuit, this achievement represents an important milestone in quantum supremacy, paving the way for significant advancements in cryptography, simulations, and the optimization of complex processes.
