Water molecule case study to be presented at Q2B Copenhagen 2026 shows how error mitigation can dramatically improve the reliability of quantum chemistry on today’s processors

TEL AVIV, Israel and COPENHAGEN, Denmark, Sept. 9, 2026 /PRNewswire/ — Qedma Quantum Computing, a pioneer in quantum error reduction software, together with the HQC2 team at University of Copenhagen (KU), Denmark, Technical University of Denmark (DTU) and University of Southern Denmark (SDU), today published the findings of a collaborative study that delivered accurate quantum chemistry results, demonstrating the value of error mitigation in quantum computation. Qedma’s researchers will be presenting this work and a separate talk on quantum advantage at Q2B Copenhagen, September 9-10, 2026.

In the study, researchers at HQC2 and Qedma explored the potential energy surface of a water molecule using an orbital-optimized variational ansatz on IBM’s Aachen quantum processor with Qedma’s QESEM error reduction software. Led by Prof. Stephan P. A. Sauer and postdoctoral researcher Renato Olarte Hernandez at University of Copenhagen (KU), together with Prof. Sonia Coriani and postdoctoral researcher Emanuele Rossi at the Technical University of Denmark (DTU), the study was carried out as part of Q-CHEMION, a project under the Eureka open call for applied quantum technologies.

The research achieved exceptionally high accuracy for quantum computation, a 30–50× improvement over the raw results achieved without QESEM error mitigation.

Today’s quantum processors are noisy, which can make quantum chemistry calculations unreliable and inaccurate. QESEM mitigates the impact of noise in current quantum computers. Rather than waiting for large-scale, fully fault-tolerant quantum computers, QESEM’s patented approach unlocks the ability to execute larger and more complex quantum workloads while producing accurate results. It is currently being used by leading enterprises, academic institutions, and research laboratories around the world.

“We’re extremely pleased with the results of this collaborative study that clearly illustrates how our error mitigation software can help bridge the gap between today’s noisy quantum devices and the high-accuracy quantum computations required for future scientific applications,” said Qedma CEO and Co-founder Dr. Asif Sinay. “The work shows a strong proof of concept for applying quantum computing to quantum chemistry on current hardware, demonstrating improved accuracy as higher levels of precision were required.”

“Accuracy is particularly important in quantum chemistry, where even relatively small errors can affect the reliability of calculated molecular properties and energies,” said Prof. Stephan P. A. Sauer, KU. “This study allowed us to explore how error mitigation can improve the accuracy of chemistry calculations performed on today’s noisy quantum hardware. The results demonstrate the potential of approaches such as QESEM to help achieve the high levels of precision required for quantum chemistry applications.”

Qedma recently demonstrated quantum advantage together with IBM, accurately resolving the dynamics of quantum materials unseen in classical simulation. The results marked the first time quantum advantage has been achieved with commercially available hardware and software, reaching a paradigm where multiple state-of-the-art classical approaches failed to provide consistent, reliable answers.

MUMBAI, India, Sept. 9, 2026 /PRNewswire/ — The National Bank for Financing Infrastructure and Development, India’s premier development financial institution set up by the Government of India in 2021 to accelerate investment in the country’s infrastructure sector, proudly announces the third edition of its flagship annual event – Infrastructure Conclave 2026. This year’s event, to be held in Mumbai on Thursday, September 17, 2026, is designed to advance conversations on India’s infrastructure development by bringing together key stakeholders to exchange insights and shape the sector’s future growth trajectory.

Speaking on the occasion, Shri Rajkiran Rai G., Managing Director, National Bank for Financing Infrastructure and Development, said, “India’s journey towards becoming a developed nation will be shaped by its ability to build resilient infrastructure supported by deep, diversified pools of long-term capital. As financing models evolve, stronger collaboration between government, regulators, institutional investors and financial markets will be critical in unlocking the next phase of infrastructure growth. The Infrastructure Conclave 2026 reflects our commitment to advancing innovative financing solutions, strengthening market ecosystems, and catalysing sustainable infrastructure investment for India’s future.”

The Conclave will feature keynote addresses by Shri. Tuhin Kanta Pandey – Chairman, Securities and Exchange Board of India, Shri Ajay Seth – Chairman, Insurance Regulatory and Development Authority of India and Shri Challa Sreenivasulu Setty – Chairman, State Bank of India. Subsequently, panel discussions will host a distinguished lineup of speakers, including senior government officials, institutional investors and infrastructure financing leaders. The discussions will focus on bridging India’s infrastructure financing gap through domestic and global capital, mobilising insurance capital for sustainable infrastructure, structured financial solutions including securitisation, asset monetization for states and enhancing governance frameworks for development of urban infrastructure.
