Xanadu and DISCO have partnered to develop advanced wafer processing techniques aimed at improving the performance and scalability of photonic integrated chips for quantum computing. The collaboration targets key manufacturing challenges including wafer dicing, heterogeneous integration, and ultra-smooth surface polishing—critical factors for reducing optical losses in photonic devices. By refining these processes, the companies aim to enable high-volume, high-performance photonic chip packaging suitable for quantum and other cutting-edge photonic applications.
The partnership leverages DISCO’s precision manufacturing technologies—Kiru (cutting), Kezuru (grinding), and Migaku (polishing)—to improve chip singulation and eliminate the need for manual polishing. These capabilities are designed to meet the stringent optical performance requirements of photonic quantum computing, while also streamlining manufacturing for scalability. Xanadu expects the improvements to support its long-term objective of delivering a utility-scale photonic quantum computer.
Christian Weedbrook, CEO of Xanadu, said, “Our close collaboration with DISCO Corporation has helped us continuously push the boundaries of photonic packaging capabilities with their leading-edge dicing, grinding, and polishing solutions.” Steve Latina of DISCO USA added that Xanadu’s pursuit of “every photon counts” performance drives advancements across the semiconductor manufacturing ecosystem.
