Qedma, Danish Researchers Cut Quantum Chemistry Errors 30-50x

Tel Aviv – September 12, 2026 -- Qedma Quantum Computing and Denmark's HQC2 consortium have achieved a 30 to 50-fold improvement in quantum chemistry accuracy on a live quantum processor, using error mitigation software to tackle one of the field's most persistent barriers to commercial adoption.

Researchers modeled a water molecule's potential energy surface on IBM's Aachen quantum processor

The study applied an orbital-optimized variational ansatz combined with Qedma's QESEM error reduction software, running on IBM's Aachen quantum processor. The work was led by Prof. Stephan P. A. Sauer and postdoctoral researcher Renato Olarte Hernandez at the University of Copenhagen, alongside Prof. Sonia Coriani and postdoctoral researcher Emanuele Rossi at the Technical University of Denmark. The project falls under Q-CHEMION, part of the Eureka open call for applied quantum technologies.

Cleveland – September 12, 2026 -- A research team from Cleveland Clinic, RIKEN and IBM has been named a finalist for the 2026 ACM Gordon Bell Prize after simulating a 12,635-atom protein complex, the largest biologically meaningful molecule ever modeled using quantum computers. The winner will be announced at SC26 in Chicago, running Nov. 15-20, 2026.

Quantum-classical hybrid method scales computation 40-fold in under a year

The team's approach, called quantum-centric supercomputing, combines IBM Quantum Heron processors with classical supercomputers Fugaku and Miyabi-G, operated respectively by RIKEN and a University of Tokyo-University of Tsukuba consortium. The quantum systems executed up to 94 qubits and nearly 6,000 quantum operations on portions of the calculation critical to accuracy, while the classical machines reassembled full molecular representations.
