At QNS, we specialize in delivering quantum computing solutions for electronic

structure calculations: a cornerstone challenge in quantum chemistry and materials discovery. Harnessing the quantum-mechanical nature of molecular systems, our algorithms provide unmatched accuracy and scalability in predicting electronic properties essential to drug discovery, catalysis, energy storage, and molecular design.

Our Mission

Our mission is to revolutionize the modeling of molecular electronic structure through quantum-native algorithms, enabling scientists to simulate molecular systems with chemical accuracy that far exceeds the limits of traditional methods such as Hartree-Fock or Density Functional Theory (DFT).

Our Vision

 we are committed to pushing the boundaries of molecular modeling. Our quantum-first approach empowers R&D teams across chemistry, biotech, and clean tech to explore new molecular landscapes with precision and speed that redefine possibility. We are building the quantum infrastructure for the chemistry of the future. 

Scientific Foundations
