TerraSky Co.,Ltd <3915> was bid-only at its daily limit-up of 2,563 yen, up 500 yen from the previous session. The company announced around 11:10 a.m. that its group firm Quemix developed foundational technology for molecular dynamics (MD) simulations on quantum computers through joint research with DENSO CORPORATION <6902>. It also disclosed the development of a new technology called QAVG with Mitsui Kinzoku Company, Limited <5706> to streamline quantum-based materials development, while joint research with TOYOTA MOTOR CORPORATION <7203> and the University of Tokyo yielded new guidelines for efficient computational resource allocation across classical and quantum devices. The announcements triggered heavy buying.

Quemix and DENSO created a quantum-classical hybrid MD framework to combine quantum and classical systems, achieving highly accurate chemical state predictions with a low computational load. The company said the breakthrough paves the way for advanced quantum computing applications in fields requiring atomic-level precision, such as next-generation battery materials, polymers, catalysts, and drug discovery.

The QAVG technology developed with Mitsui Kinzoku is an enhanced version of quantum phase estimation (QPE), a core method for quantum materials calculations. While conventional QPE faces surging gate operations and computational costs as energy resolution improves, QAVG enables high-precision, high-speed calculations using dynamical mean-field theory (DMFT) on quantum computers while curbing cost increases. TerraSky noted that while DMFT's long processing time had been a bottleneck, the QPE performance boost opens prospects for early practical application.
