Core Insights - The research team from the University of Pennsylvania and CUNY has proposed an innovative "classical-decisive" quantum internet architecture, marking a significant step towards the practical and scalable development of quantum communication [1][4]. Group 1: Quantum Internet Challenges - The development of traditional quantum internet faces three core challenges: the fragility of quantum states, hardware compatibility and scalability, and the lack of synergy between quantum and classical communication [3]. - Quantum states are easily disrupted by environmental noise, leading to decoherence and unreliable information transmission [3]. - Early quantum communication systems rely on discrete optical components, making them large, power-hungry, and unstable, hindering miniaturization and mass production [3]. - Effective collaboration between quantum and classical layers is essential for key distribution, network routing, and error correction, yet remains a significant challenge [3]. Group 2: Integrated Photonics as a Solution - Integrated photonics is identified as a key technology to address these challenges, allowing for the integration of optical components on a single chip, enhancing system stability, scalability, and cost-effectiveness [3]. Group 3: Innovations in Architecture - The research introduces a "dual-track" collaboration between quantum and classical channels, redefining their relationship and enhancing the stability and operability of quantum communication [5][8]. - The quantum channel is responsible for transmitting quantum entanglement or keys, while the classical channel transmits deterministic control information, ensuring high-speed and reliable information exchange [6][7]. Group 4: Hardware Implementation - The research team successfully integrated quantum light sources, modulators, detectors, and classical control circuits onto a single photonic chip, significantly reducing the system's size and power consumption [9][11]. - The quantum light source generates entangled photon pairs with high brightness and purity, providing a reliable quantum carrier for communication [9]. - The integration of photodetectors and electro-optical modulators on the chip facilitates efficient conversion between quantum optical signals and classical electrical signals [10]. Group 5: Performance Breakthroughs - The system achieves near 100% success probability in quantum communication through deterministic control, significantly reducing communication delays and resource consumption [12]. - The modular design of the integrated photonic chip allows for rapid deployment of quantum nodes and linear network expansion, laying the groundwork for a global quantum internet [12]. Group 6: Industry Impact - The development of the "classical-decisive" quantum internet is expected to transition quantum technology from laboratory experiments to a widely accessible infrastructure, potentially revolutionizing secure communication, computational capabilities, and sensing precision [14].

Core Viewpoint - The article emphasizes the importance of state-owned enterprises (SOEs) in driving high-quality development through technology innovation and industry integration on the Sci-Tech Innovation Board [1][2]. Group 1: Industry Mergers and Acquisitions - SOEs are accelerating the cultivation of new productive forces by actively engaging in mergers and acquisitions on the Sci-Tech Innovation Board [2]. - In January 2025, China Telecom's subsidiary, Quantum Group, officially took over "the first stock in quantum communication," Guoshield Quantum, to build new industry synergies in the quantum communication field [2]. - In 2024, Zhongke Star Map and its subsidiaries acquired seven companies to enhance their industry chain and broaden application areas, reinforcing a dual-driven development model of "internal growth + external expansion" [2]. Group 2: Quality Improvement and Efficiency - Improving the quality of listed companies is fundamental for the long-term healthy development of the capital market, with SOEs playing a leading role [3]. - Nearly 40 SOE companies on the Sci-Tech Innovation Board disclosed their annual action plans for "quality improvement and efficiency enhancement" in 2024 [3]. - SOEs have established a good benchmark for investor returns, with many maintaining a cash dividend ratio exceeding 20% and repurchasing nearly 100 million yuan worth of stocks in recent years [3]. Group 3: Market Value Management - Effective market value management requires enhancing internal operational efficiency and improving external communication with investors [6]. - SOEs are encouraged to strengthen their internal capabilities and improve operational quality to gain market and investor recognition [6]. - A representative from an SOE shared that their company established a market value management leadership group and improved information disclosure, leading to positive outcomes in market performance and institutional holdings [6]. Group 4: Future Support and Policy Implementation - The Shanghai Stock Exchange will continue to support SOEs in enhancing operational quality and increasing social value [4][7]. - The exchange plans to implement policies such as the "Eight Measures for the Sci-Tech Innovation Board" and "Six Measures for Mergers and Acquisitions" to optimize institutional inclusiveness and adaptability [7].
