OpenGovAsia: China’s Progress in Quantum Technology

By IQT News posted 21 Sep 2021

(OpenGovAsia) OpenGovAsia provides a review of China’s achievements in quantum technology which IQT-News summarizes here.
In recent years, China has achieved a series of breakthroughs in quantum technology, including the world’s first quantum satellite, a 2,000-km quantum communication line between Beijing and Shanghai, and the world’s first optical quantum computing machine prototype.
A hub for China’s quantum technology is home to over 20 quantum technology enterprises and achieved an output value of some 430 million yuan (about $66.5 million) in 2020. The quantum information technology is to be further integrated, convenient and low-cost, allowing more people to have access to it.
China’s quantum company has tried out the quantum encryption calls in 15 provinces and has garnered some 10,000 users. The users can have secure calls and messages encrypted with quantum keys after inserting a SIM card and installing a related app, which can ensure information security.
Besides quantum communication, quantum precision measurement and quantum computation have also seen great breakthroughs in industrial applications. Quantum precision measurement instruments can achieve nanoscale high spatial resolution and single spin ultra-high detection sensitivity, which has been applied to study magnetic and superconducting materials.
Chinese scientists have set up an integrated quantum network that combines 700 fibre and two ground-to-satellite links and realised quantum key distribution between more than 150 users over a combined distance of 4,600 km.
A global quantum network can be realised by connecting more national quantum networks from different countries via ground connections or ground-to-satellite links. In the future, quantum communication will be applied in fields of finance, political affairs and national defence. A whole industry chain and eventually a truly secure quantum internet will be possible.

As reported by OpenGov Asia, China issued a guideline that detailed measures to promote the region’s economic growth, scientific and technological innovation, urbanisation, green development, opening-up, and people’s well-being. By 2025, the comprehensive strength and competitiveness of the region should be further enhanced, and marked progress should be achieved in innovation capacity.
