What is Packaging & Interconnect?

DARPA and Xanadu are shifting quantum competition toward the packaging, interconnect, and manufacturing layers that determine whether systems can scale reliably beyond the lab. Validation is moving from qubit counts to industrial-grade packaging and interconnect performance. DARPA is tying funding to hard milestones, audits, and scalable modular architectures. Xanadu is investing in photonic packaging and 300 mm manufacturing to cut loss and improve yield. Networking IP, packaging yield, and supply-chain execution are becoming key value pools. Procurement will favor platforms with credible paths to scalable, integrated deployment.

DARPA and Xanadu Put Packaging and Interconnect Under the Microscope

Quantum competition is moving down the stack, where packaging, interconnects, and manufacturing execution now decide who can scale.
