Quantum Interconnects Link Two 120-Qubit Processors (IBM Research)

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... » read more
