# IBM reports improved processor links for modular quantum computing

_Published Wednesday, November 11, 2026 at 9:18 AM EST · Science · Latest · Tier 2 — Notable_

IBM says it connected two Nighthawk quantum processors with four links, achieving an average 1% error rate and a best result of 0.7%. The company reports that raw error rates improved by about a factor of 2x over prior demonstrations, alongside more repeatable attachment of the links.

The work supports IBM's modular approach to Starling, its planned 2029 quantum computer. IBM also says improved error-correction code reduces required connections between qubits from six to five while delivering 20x-100x lower logical errors. Scaling remains a substantial hurdle: Starling will need over 100 links per module with 0.1% error rates.
