Tom Darras (Welinq): Scaling quantum computers by networking shared entanglement

AI-summarised brief · reviewed before publication

In a recent interview, Tom Darras, CEO and co‑founder of Welinq, outlined the company’s approach to scaling quantum computers through quantum networking that shares entanglement across processors. Welinq is building a full stack—including qubit‑photon interfaces, optical links, entangled photon sources and long‑lived quantum memories—to create modular, scale‑out clusters and provide quantum‑safe links between data centers. The firm tracks key performance metrics such as entanglement generation rate, fidelity and memory lifetime, and has developed the Arachne compiler to distribute quantum circuits across multiple QPUs. Darras said the technology supports both homogeneous and heterogeneous quantum systems and is already being piloted in “quantum‑augmented” data centers that interconnect regional facilities over metropolitan distances.

💡 Why It Matters

  • · By turning entanglement into a networking resource, Welinq enables quantum processors to combine computational power without building monolithic machines, opening a practical path to large‑scale quantum computing and secure data‑center communications.
