Beijing: Chinese scientists claim to have created the world’s first light-based quantum computer which can solve problems far faster than a classical supercomputer, an advance hailed by experts as a “major achievement” that provides a fundamentally different approach to designing such powerful machines, the official media reported on Saturday.
Jiuzhang, the quantum computer, can reliably demonstrate “quantum computational advantage”, a milestone in computing, state-run China Daily quoted a study published in the journal Science.
Quantum computers excel at running simulations that are impossible for conventional computers, leading to breakthroughs in materials science, artificial intelligence and medicine.
Jiuzhang takes its name from an ancient Chinese mathematical text. It can perform an extremely esoteric calculation, called Gaussian boson sampling, in 200 seconds. The same task would take the world’s fastest classical supercomputer Fugaku around 600 million years, the report…
