Chinese scientists announced on the 4th that a prototype of 76 photons (qubits) has been built. In terms of speed, it only takes 200 seconds to solve the mathematical algorithm Gaussian boson sampling, while the current supercomputer takes 600 million years. It is generally believed that 50 qubits are the key threshold for quantum computers to surpass traditional computers. "Nine chapters" is named after a famous mathematical monograph in ancient China.
