Microsoft & Quantinuum: 12 Logical Qubits + First Hybrid Chemistry Simulation
Microsoft and Quantinuum tripled their record to 12 LQ on Quantinuum's 56-qubit H2, with a 22× improvement over base error rates. Two LQ drove the world's first end-to-end quantum-AI-HPC chemistry simulation, estimating an iron catalyst's ground-state energy within chemical accuracy.
