Switch Point

Inside Cisco's Santa Monica quantum lab: the case for scaling quantum computing by connecting processors, and the prototype quantum switch intended to route entanglement across existing fiber infrastructure.

Cisco StoryLab’s long-form account follows Vijoy Pandey, Ramana Kompella, and Reza Nejabati as the team develops the components of a quantum networking stack in Santa Monica.

The switch point is the architectural shift from pursuing ever-larger isolated quantum processors toward interconnecting processors and sensors. The article describes a room-temperature quantum switch prototype designed to route entangled photons without measuring their state, complementing Cisco’s entanglement source and network software. These are reported early technical milestones, not evidence of a completed large-scale quantum internet.

Why this belongs here: It is a narrative bridge between the scientific objective (scaling quantum computing), the enabling physical device (a quantum switch), and the network architecture needed for distributed quantum systems. It may be worth highlighting in the Quantum Computing frontier narrative, not merely listing chronologically.
