QuantumML: Machine Learning for Quantum Materials Discovery

Fri, 01 Sep 2023 00:00:00 +0000

Project Mission

The QuantumML project aims to revolutionize materials discovery by combining quantum mechanical calculations with advanced machine learning to identify novel quantum materials with tailored electronic, magnetic, and optical properties.

Scientific Challenge

Quantum materials exhibit exotic properties like superconductivity, topological insulation, and quantum magnetism that could enable:

Fault-tolerant quantum computers
Room-temperature superconductors
Ultra-efficient solar cells
Next-generation batteries

However, the vast chemical space (>10^60 possible compounds) makes experimental exploration impossible. Our ML-guided approach reduces this search space by orders of magnitude.
