Quemix and Mitsui Kinzoku have introduced QAVG, a technique that optimizes Quantum Phase Estimation within Dynamical Mean-Field Theory to significantly reduce computational costs while maintaining high accuracy. Validated on Quantinuum hardware, this approach effectively bypasses the traditional trade-off between energy resolution and processing time, accelerating materials discovery timelines. The development marks a practical step toward making highly accurate DMFT simulations feasible on current quantum hardware without waiting for future hardware scaling.
Quemix’s QAVG Suppresses Computational Cost in DMFT

Quemix & Mitsui Kinzoku developed QAVG, a new technique for Dynamical Mean-Field Theory (DMFT) calculations, that suppresses computational cost.
Quemix Inc. and Mitsui Kinzoku Company, Limited have jointly developed a new technology, QAVG (QPE Averaged over Variable Grids), designed to accelerate materials discovery using quantum computers. Traditionally, the highly accurate Dynamical Mean-Field Theory (DMFT) method has been limited by lengthy computation times, a challenge these companies specifically addressed through improvements to Quantum Phase Estimation (QPE), a key component of the process. The resulting technology allows for both high-speed and high-accuracy…
