Harvard Develops Ultra-Thin Chip to Advance Quantum Computing

Quick Summary

• Researchers at Harvard SEAS utilized metasurfaces for creating scalable quantum optical networks.
• Metasurfaces eliminate the need for conventional components like waveguides, beam splitters, and extended optical chips by integrating them into single ultra-thin arrays.
• The study was led by Federico Capasso and funded by the Air Force Office of Scientific Research (AFOSR).
• Graph theory was employed too design these metasurfaces,allowing precise control over photon behaviors and predicting experimental results.
• The research suggests that metasurface-based devices could overcome scalability issues in quantum computing while being cost-efficient, robust, and simpler to fabricate.
