🔬 How can quantum computing tackle the ground state problem in strongly correlated systems? Finding ground states of quantum many-body systems is fundamental to physics and chemistry, yet classical methods often hit computational walls when dealing with strong correlations. This challenge directly impacts materials discovery and molecular design – areas crucial for industrial innovation. We at QUTAC are proud to share new research from our Material Science Working Group that explores Quantum Imaginary Time Evolution (QITE) as a promising approach for quantum computers. The study provides a comprehensive benchmark of QITE's capabilities across various lattice and molecular systems, including a simplified model of the 2D magnetic material CrI₃ and industrially relevant molecules like Fe(III)-NTA. Key findings show that even with current algorithmic limitations, QITE can achieve dramatic improvements in state fidelity for certain strongly correlated systems. Particularly exciting: the algorithm shows promise for materials with nearest-neighbor interactions – exactly the types of systems relevant for next-generation magnetic materials and spintronics applications. This work represents the collaborative strength of QUTAC, bringing together expertise from: Michael Kaicher & Michael Kühn (BASF) Florian Dommert (TRUMPF) Christopher Wever & Maximilian Amsler (Bosch Research) Their rigorous analysis helps chart a realistic path toward practical quantum advantage in materials science, identifying both opportunities and challenges that need addressing as we move toward fault-tolerant quantum computers. Thanks to everyone involved in the process!
