en.Wedoany.com Reported - China Telecom has launched a new photonic quantum computer, the "Tianyan-P2000," capable of manipulating 2,682 photons, which is now accessible to researchers worldwide via its cloud platform. The system completed a complex calculation in 29 microseconds, a task that would take the most powerful classical supercomputer an estimated 16 billion years to finish. This marks the launch of China's first online service to achieve quantum advantage using photonic technology, offering a potential alternative to superconducting systems that require extreme cooling.

The Tianyan-P2000 is based on the core architecture of Jiuzhang 4.0, a prototype previously highlighted in the journal Nature for outperforming classical computers on specific tasks. Huang Wenya, senior product manager of the Tianyan Quantum Cloud Platform, stated that with the launch of the Tianyan-P2000, the platform has become the world's first cloud platform capable of simultaneously offering quantum advantage services through both photonic and superconducting technologies. Currently, the Tianyan-P2000 serves research institutions, universities, and enterprises, with applications already deployed in areas such as graph data analysis, drug discovery, and machine vision. The platform has accumulated over 50 million visits and processed more than 4 million experimental tasks for users from over 60 countries and regions.

China Telecom Quantum Group stated that this photonic approach operates at room temperature and offers longer coherence times, providing advantages in cost and scalability. Quantum control engineer Liu Chunwang noted that photonic quantum computing can run at room temperature, contrasting with superconducting systems that require extreme low temperatures, helping to reduce operational costs and expand accessibility. Additionally, the photonic approach of the Tianyan-P2000 boasts longer qubit coherence times and lower noise, which aids in maintaining the accuracy of quantum computations. The system's ability to sustain qubit coherence over extended periods enhances its potential for performing complex calculations and obtaining reliable results.
