Harvard researchers found a way to correct for signal loss with a prototype quantum node that can catch, store and entangle bits of quantum information. The research is the missing link towards a practical quantum internet and a major step forward in the development of long-distance quantum networks

I've been trying to keep up with this research for years, but in the last 10-12 months it's moving at incredible speeds. (No pun intended)

For those not familiar with network protocols and network models, here's the standard OSI network model https://en.m.wikipedia.org/wiki/OSI_model What this Harvard research does is pave the way for OSI Level 1 - the physical network transport model. (The quantum equivalent of physical ethernet wires.The wires do it through passing electrical current, an equivalent quantum entanglement layer 1 would do it thru mechanisms that measure quantum entanglement. )

There are already theoretical papers out there now to allow the quantum network model to crawl up the OSI stack very quickly.

Basically, this paves the way for near instantaneous IP communication. And, uh, theoretically anywhere. So, yeah Kirk, no subspace communication required.
