CavilinQ is a quantum hardware company building cavity-enhanced photonic interconnects that link individually isolated quantum processors into modular, large-scale distributed quantum systems. Its architecture combines precisely controlled arrays of neutral atoms with optical cavities, and the name derives from 'Cavity-Link' with a Q for quantum. Founded in 2025 and based in Cambridge, Massachusetts, it closed an $8.8M seed round led by QVT with Safar Partners, MFV Partners, Serendipity Capital, and Harper Court Ventures. The capital funds a dedicated Cambridge lab and engineering hires to reach production-ready prototypes.
What sets it apart
High-fidelity light-matter interfaces implemented as cavity-enhanced photonic links, letting separate quantum processors operate as one cluster and sidestepping the physical scaling ceiling of single-processor architectures.
Interconnect hardware that uses optical cavities and high-fidelity light-matter interfaces to entangle and link separate quantum processors, initially demonstrated with neutral-atom processors.
