Simulations across 14 materials demonstrate that high-fidelity quantum algorithms no longer require supercomputing clusters, democratizing access to next-generation materials discovery
TORONTO, Aug. 18, 2026 (GLOBE NEWSWIRE) -- OTI Lumionics, a leader in advanced quantum simulations and solutions for next-generation materials discovery, in collaboration with the Samsung Advanced Institute of Technology (SAIT), today announced the publication of a new manuscript benchmarking its proprietary Iterative Qubit Coupled Cluster (iQCC) method in the Journal of the American Chemical Society (JACS). By validating a computational method that is significantly less hardware-intensive, this joint research unlocks the potential to accelerate the discovery of materials for next-generation consumer electronics, such as OLED displays, without relying on cost-prohibitive supercomputing clusters.
Building on previous work published in the Journal of Chemical Theory and Computation (JCTC), the new study benchmarked the iQCC method against classical approaches across 14 OLED emitter materials. The results highlight a massive leap in memory and processing efficiency. The optimized C++ version used in this study executed 200+ qubit emulations using a single commercial AMD CPU chip with 32 CPU processes and approximately 800GB of RAM. This approach drastically reduces the hardware requirements for high-accuracy quantum simulations. OTI Lumionics further validated this methodology through its recent implementation of iQCC on ready-accessible Blackwell systems. The team demonstrated a 90x performance increase over traditional CPU environments, reducing complex 112-qubit ground-state calculations to approximately one hour. This advancement builds directly on the foundational chemistry and experimental data validated through the collaboration with SAIT.
