Scientists Enable Atoms to Communicate in Silicon Chips

Rapid Summary

• engineers at UNSW have created ‘quantum entangled states’ using the spins of two atomic nuclei, marking a notable advancement for quantum computing.
• Published in Science (September 18), the breakthrough is pivotal for building large-scale adn scalable quantum computers.
• The research uses silicon chips implanted with phosphorus atoms to encode quantum information via nuclear spin-the most isolated and clean quantum objects in solid-state.
• A key challenge for prior methods was balancing isolation from noise while enabling meaningful interactions between computing elements for scalability.
• The team demonstrated that electrons could facilitate interaction between distant atomic nuclei at scales consistent with current semiconductor manufacturing processes (e.g., 20 nanometers).
• This method circumvents previous limitations requiring close placement of atomic nuclei to interact with one electron,offering scalability aligned with conventional chip manufacturing systems.

Indian Opinion Analysis
The growth at UNSW represents a transformative leap in the global race toward scalable quantum computing by harmonizing robustness and compatibility with existing semiconductor infrastructure-a factor critical for achieving real-world applicability at industrial scale. For India, this advance underscores the importance of investing both financially and intellectually into emerging technologies like silicon-based quantum platforms, possibly leveraging its burgeoning tech sector to contribute to similar foundational breakthroughs.
