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

Quantum Zeitgeist4 min read

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…
