量子光芯片，全球首颗

Core Viewpoint - The article discusses the development of the world's first integrated electronic-photonic-quantum chip by researchers from Boston University, UC Berkeley, and Northwestern University, marking a significant step towards practical quantum systems [2][4]. Group 1: Chip Development - The chip utilizes standard 45-nanometer semiconductor technology to integrate quantum light sources with stable electronic devices on a single platform [3][11]. - Each chip contains twelve independent quantum light sources, each less than one square millimeter in size, driven by lasers and utilizing micro-ring resonators to generate photon pairs [7][10]. Group 2: Technical Innovations - The team embedded a real-time control system directly into the chip to address the sensitivity of resonators to temperature changes and manufacturing variations, ensuring stable quantum processes [9][10]. - The integration of photonic devices with classical electronic technology posed significant challenges, requiring a rethinking of how these technologies coexist on the chip [11][12]. Group 3: Collaborative Efforts - The project involved collaboration across various fields, demonstrating that complex quantum photonic systems can be constructed and stabilized entirely within CMOS chips [12]. - Several student researchers from the project have transitioned to the industry, continuing work in silicon photonics and quantum computing at companies like PsiQuantum, Ayar Labs, and Google X [12]. Group 4: Support and Funding - The research received support from the National Science Foundation, Packard Fellowship, and GlobalFoundries, highlighting the importance of funding in advancing quantum technology [13].
