It took less than a second to solve a puzzle that super computers would take five years to solve.
Known as a qubit, it allows basic information to represent all possibilities simultaneously, theoretically, making them faster than conventional computers.China's Jiuzhang first shot to fame in 2020, when the research team led by Jianwei performed Gaussian boson sampling in 200 seconds. The same on a conventional supercomputer would take an estimated 2.5 billion years.
They put Jiuzhang to the test by implementing two algorithms commonly used in AI- random search and simulated annealing. These algorithms can be a challenge even for supercomputers, and the researchers decided to use 200,000 samples to solve it.
