Why it matters
Quantum systems need memory and interconnects as processors grow into networks. Photon Queue has early customer deployments, but the seed round must turn precision lab optics into repeatable hardware.

Photon Queue announced Tuesday that it closed a $4 million seed round led by Playground Global, giving Nathan Arnold and three fellow University of Illinois quantum researchers fresh capital to manufacture a component most quantum-computing roadmaps assume will eventually exist: memory for storing and synchronizing individual photons.…
