On December 7th, the reporter learned from China Telecom Quantum Information Technology Group Co., Ltd. (hereinafter referred to as "China Telecom Quantum Group") that during the 2024 Digital Technology Ecology Conference held recently, the company officially released the superconducting quantum computer "Tianyan 504" with the highest single bit count in the country, marking its global leading ability in quantum computer manufacturing and delivery. In April this year, the Institute of Quantum Information and Quantum Technology Innovation of the Chinese Academy of Sciences delivered a 504 bit superconducting quantum computing chip "Xiaohong" to Keguodong Quantum Technology Co., Ltd. (hereinafter referred to as "Guodun Quantum"), which is used to verify the core hardware such as the kilobit measurement and control system independently developed by Guodun Quantum, and plans to build a complete machine to access the China Telecom quantum cloud platform. Based on the "Xiaohong" chip, China Telecom Quantum Group and Guodun Quantum have jointly developed the largest single bit superconducting quantum computer in China, the "Tianyan 504", which will be opened to the world through the "Tianyan" quantum computing cloud platform. Lv Pin, Chairman of China Telecom Quantum Group, introduced that in November 2023, China Telecom released the world's first super fusion cloud platform with quantum superiority capability - the "Tianyan" quantum computing cloud platform. Through the integration of "Tianyi Cloud" super computing power and 176 superconducting quantum bit computing power, it provides convenient and simple quantum computing services for various users. With the upcoming integration of 504 bit real machines into the "Tianyan" quantum computing cloud platform and its external services, the platform will achieve a dual upgrade in computing power scale and types. The largest quantum computing cluster in China, consisting of one 24 bit, two 176 bit, and one 504 bit, will provide five world-class high-performance simulation machines and Cqlib quantum programming frameworks, which will be another leap in China's quantum computing capabilities. Lv Pin introduced that since the launch of the "Tianyan" quantum computing cloud platform, it has received over 12 million visits from more than 50 countries around the world, with more than 600000 experimental tasks. Accelerating the commercialization of quantum computing is an important task for China Telecom Quantum Group. At present, the company has launched quantum computing products and services, including the delivery and operation of independently controllable Tianyan series quantum computing machines, serving the new computing power center of four computing fusion; Based on the "Tianyan" cloud platform, we provide various types of quantum computing power to serve universities and research and development institutions; Develop quantum computing application solutions in fields such as education, meteorology, electricity, and AI. Looking towards the future, we will accelerate the process of practical and commercial application of quantum computing, and contribute to the acceleration of the formation of new quality productivity for this disruptive technology L ü Pin said.
