IBM CEO Claims Major Quantum Computing Breakthrough, Simulates 12,000-Atom Protein

At New York Tech Week on Tuesday, IBM CEO Arvind Krishna stated the company has achieved a significant quantum computing milestone, simulating a protein complex containing 12,000 atoms—a substantial leap from roughly 300 atoms modeled at the end of 2025. According to Barron's, Krishna said IBM has convinced itself it can complete the necessary scientific research to advance quantum technology, which the company believes will deliver substantial returns.

The breakthrough came from an experiment collaborating with Cleveland Clinic and RIKEN, simulating trypsin and T4-lysozyme protein behavior in liquid water. IBM received $1 billion in U.S. government funding this month to support its Anderon quantum chip foundry. Meanwhile, Quantinuum, the first pure-play quantum company to go public via traditional IPO rather than SPAC, opened with a 13% gain on Thursday but closed up less than 1%, and fell 6.8% on Friday, signaling divergent market sentiment toward quantum technology.
