As long as you replace a quantum secure SIM card and activate quantum services, you can use quantum encryption technology to protect the security of communication content; On the big screen of Hefei Quantum Metropolitan Area Network, dotted lines jump one by one, showing the flow of data under quantum network encryption; The Tianyan 504, the quantum computer with the highest number of qubits in China, is quietly operating... Recently, reporters followed the "Entering New State owned Enterprises - Brand Leadership, Intelligent Chain Future" activity organized by the State owned Assets Supervision and Administration Commission of the State Council to enter China Telecom Quantum Group, a subsidiary of China Telecom, to experience the mysterious charm of quantum technology up close. In the future, quantum communication networks will serve the integrated information network of heaven and earth, providing information security guarantees for it. ”Peng Chengzhi, Professor at the University of Science and Technology of China and Chief Scientist of China Telecom Quantum, said. The staff introduced that based on quantum encryption technology, China Telecom Quantum Group has launched the world's first quantum encrypted secure communication and office application - "Quantum Secure Communication". Quantum Confidential Communication has been integrated and applied in hundreds of industries such as government affairs, emergency response, and finance, with a user base of over 5.5 million and more than 3000 service units. Not only that, China Telecom Quantum Group has built the world's largest quantum secure communication metropolitan area network in Hefei - Hefei Quantum Metropolitan Area Network, providing quantum security access services for more than 500 party and government agencies and grassroots units. The group has also launched a quantum cloud seal that integrates quantum encryption, artificial intelligence, digital printing control and other technologies. The related technologies have been promoted and used in government approval, rural governance, financial auditing, enterprise process management and other scenarios in Anhui, Beijing, Shaanxi, Heilongjiang, Hebei and other places. In addition to laying out quantum communication technology, China Telecom Quantum Group is also accelerating the commercialization of quantum computing. The staff introduced that China Telecom Quantum Group has launched the world's first super converged cloud platform with quantum computing advantages - the "Tianyan" quantum computing cloud platform. The platform is connected to a 24 bit, two 176 bit, and one 504 bit quantum computers, which form an 880 bit superconducting quantum computing cluster. At the same time, the platform is based on Tianyi Cloud's excessive computing power scheduling capability, achieving efficient hybrid scheduling of classical computing and quantum computing power. At present, the "Tianyan" quantum computing cloud platform has exceeded 30 million visits, covering users from more than 60 countries at home and abroad, and the number of experimental tasks has exceeded 1.6 million. It is reported that China Telecom Quantum Group is relying on the "Tianyan" quantum computing cloud platform to promote the application of quantum computing in fields such as biochemistry, material manufacturing, meteorological prediction, financial technology, and machine learning, and explore the construction of an innovative ecosystem for quantum computing applications that deeply integrates industry, academia, research, and application. For example, China Telecom Quantum Group has partnered with the meteorological department to integrate quantum computing algorithms and classical algorithms for complex scenarios such as precipitation prediction; In terms of the construction of quantum education and information science disciplines, the group has collaborated with multiple universities to create a quantum computing education system, promoting the construction of quantum computing disciplines and talent cultivation. The reporter learned that currently, China Telecom Quantum Group has laid out its layout around quantum technology related industries, technology, talent, and ecology, and has launched more than 30 quantum technology products, covering more than 10 industries such as government affairs, emergency response, industry, and finance.
