"Quantum interconnect" refers to methods for linking up smaller quantum processors into a larger system.
As of 2024, seemingly few organizations developing quantum hardware had actually integrated multiple chips in interconnects as part of their main current roadmap. But many acknowledged that this would be an essential step towards scalable compuation.
The name "quantum interconnect" is likely partly a throwback to classical computer's "chip interconnect".
