Commercial applications for quantum computing are still a distant reality, says Tencent researcher

Despite a significant breakthrough by Google in achieving quantum supremacy last month, commercial applications for the technology are still a distant reality, according to Tencent Quantum Lab director Zhang Shengyu.

“People are always talking about the possible applications, such as in materials, medicine and artificial intelligence. But how to make it a reality is a problem puzzling the world,” he said. “Scientists have never been too optimistic. I always believe we are far away from the commercial application of quantum computing.”

Quantum computing is still in an early stage, and Zhang called for open discussion and collaborative communication in order to develop the technology.

“Google undoubtedly has excellent achievements in quantum computing and is leading the globe in some ways,” Zhang said. “In general, the US and Europe, with more quantum computing scientists, outpaces China in breakthroughs and talent acquisitions.”

Tencent Quantum Lab, set up early last year, “aims to connect fundamental theory with practical applications in the fast-growing sector of quantum information technology,” according to its website.

The laboratory director’s comments, made on the sidelines of Tencent’s fourth Teng Yun Summit in Beijing, come after Google announced a major breakthrough last month – its 53-bit quantum computer Sycamore had taken just 200 seconds to perform a calculation that the world’s most powerful computer would take 10,000 years to crack.
