IBM Quantum presents a staged vision for transitioning from mitigating errors in current quantum devices to error correction and fault-tolerant computing, rather than treating these technologies as separate phases. It highlights research results including an effective reduction in error rates by approximately tenfold and a 63-fold reduction in sampling overhead in hybrid methods, while hardware, reliability, and scalability challenges remain open.
IBM Quantum reviewed a range of research, software, and educational updates in the second quarter of 2026, including the availability of a workflow for simulating a protein comprising 12,635 atoms and an experiment simulating hadron dynamics on real quantum hardware. The platform also unveiled operational metrics and new tools for improving errors and developing circuits and simulations.
