量子信号首次用互联网协议传输

Core Insights - A team of engineers from the University of Pennsylvania has successfully transitioned quantum network technology from the laboratory to practical application, marking a significant step towards building a future quantum internet [1] - The core achievement is a micro "Q chip" that coordinates the transmission of quantum information with classical data, allowing quantum signals to communicate using the language of modern internet protocols [1] Group 1 - The Q chip has been demonstrated to send quantum signals over commercial fiber networks while automatically correcting noise during transmission, packaging quantum and classical data into standard internet data packets [1] - The integration of the Q chip allows for the management of quantum signals on commercial networks using the same protocols as classical internet, indicating a move towards larger-scale experiments and practical quantum internet applications [1][2] - The challenge of expanding quantum signals has been addressed by the development of the Q chip, which coordinates a mixed information flow of classical signals and quantum particles [1] Group 2 - The mechanism of the Q chip is likened to railway transport, where classical signals act as the locomotive, guiding and navigating, while quantum information is akin to sealed containers that are securely delivered [2] - The Q chip is made from silicon-based materials and manufactured using established semiconductor processes, providing a realistic foundation for large-scale production and widespread application of the technology [2] - Currently, the network connects two buildings with one server and one node, utilizing approximately one kilometer of fiber, and can be expanded by producing more chips to integrate with existing urban fiber networks [2]
