Researchers at IBM Research published “Meter-scale quantum interconnects between large quantum processors.” Abstract Excerpt : “Modular quantum architecture requires long-distance quantum interconnects to stitch together individual processor modules. Such interconnects, long-distance couplers or L-couplers, must support coherent quantum operation over meter-scale distances and scale to multiple connections between any two modules. Here we demonstrate four L-couplers operating between two 120-qubit IBM Nighthawk R1 superconducting qubit processors. “ Find the technical paper here . October 2026.
