The Science & Challenge

Solving Complex Quantum Materials: Cu₃C₆O₆ & Kagome Metallicity

Accurately predicting the properties of quantum materials, candidates for future superconductors, energy-efficient catalysts and advanced electronic devices remains one of computational science’s greatest challenges.

• The Material Focus: Cu₃C₆O₆, a quantum material featuring a triangular lattice geometry that gives rise to potential Kagome metallicity, leading to complex quantum phenomena.
• The Classical Bottleneck: Dynamical Mean-Field Theory (DMFT) is one of the leading approaches for modeling such materials. However, solving the underlying quantum impurity problem scales exponentially with system complexity, making traditional classical calculations computationally costly for realistic simulations.

The Hybrid Workflow Solution

Sample-Based Krylov Quantum Diagonalization (SKQD, arXiv:2501.09702)

To address the impurity solver bottleneck, our team integrated a hybrid quantum-classical algorithm that leverages the complementary strengths of both architectures:

1. Quantum Subspace Sampling: SKQD running on IBM Quantum System Two uses quantum sampling to discover the most relevant electronic subspaces that capture the core physics of the material.
2. GPU-Accelerated Diagonalization: Reduced subspace problems are offloaded to DeltaAI supercomputing resources, where GPU-accelerated classical solvers compute exact diagonalizations in parallel, with drastic reductions in time and computational overhead.
3. End-to-End DMFT Workflow: The result is a seamless, practical quantum-centric supercomputing workflow capable of tackling realistic quantum materials.
