Chinese scientists claim to have created the world’s first light-based quantum computer that can solve problems much faster than a classic supercomputer, an advance hailed by experts as an ‘important achievement’ that offers a fundamentally different approach to designing such powerful machines, the official reported to the media Saturday.
Jiuzhang, the quantum computer, can reliably demonstrate ‘quantum computing advantage’, a milestone in computing, the state-run China Daily cited a study published in the journal Science.
Quantum computers excel at running simulations 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 classic supercomputer Fugaku about 600 million years, the report said.
It’s the second milestone since Google stated last year that its 53-qubit quantum computer had achieved such a breakthrough.
Jiuzhang used a new method of manipulating 76 photons to perform calculations instead of Google’s, which uses superconducting materials, the report said.
Experts cited the Chinese quantum computer as a ‘state-of-the-art experiment’ and a ‘great achievement’ in the field of quantum computing, as it proves the feasibility of photonic quantum computation, providing a fundamentally different approach to designing such powerful machines. said.
China has invested heavily in mastering quantum technology in recent years.
In 2017, China had launched a quantum communications satellite that will drive hack-proof and ultra-high security features, the Chinese Academy of Sciences (CAS) said.
The Quantum Experiments at Space Scale (QUESS) satellite is the first-ever space-to-ground test platform for quantum communications, Wang Jianyu, the project’s executive deputy chief engineer, had previously told official media.
Chinese officials claimed the quantum satellite was expected to provide fully secure, hack-free communications prompting foreign powers to monitor or intercept China’s communications systems.
Later that year, China launched a 2,000 km “hack-proof” quantum communication line between the capital Beijing and its commercial headquarters Shanghai, which cannot be overheard.
