Craig, you were on to something in the Q&A that needs to be considered: how do data centers actually get built out and does QFabric, which requires that every port be a Juniper port or it breaks, conflict with the reality of how data centers are built? Multi-vendor, pods, built out over time, etc. The use case for QFabric seems to be massive, greenfield data centers where the customer is willing to deploy a single vendor environment. Every application from mission critical to barely relevant have the same cost model. That may sound great from a Quantum theory perspective, it doesn't sound practical.
The "quantum mechanics" part refers to the way a packet flow gets through the network. Apparently, Juniper has a way for packets to consider multiple paths -- maybe even all possible paths -- similar to the way photons take all possible paths to the eye, creating the images we see. Pradeep Sindhu says quantum mechanics was the inspiration for the method, but Juniper isn't literally sending packets down all possible paths.
I did ask Sindhu if it would impress him to hear I'd taken queuing theory in college. He was kind enough to say yes.
