Workshop Description
Classical computational materials science uses density functional theory (DFT) and molecular dynamics to predict material properties, but these methods become unreliable for strongly correlated electron systems such as transition metal oxides, rare earth compounds, and novel metamaterial structures. Quantum algorithms (VQE, DMRG-inspired quantum circuits, quantum phase estimation) can in principle solve these problems exactly, but current NISQ hardware limits practical calculations to small systems with approximately 20-50 qubits of useful computation.
This workshop provides an honest assessment of quantum simulation capabilities for defence materials discovery. Participants examine where quantum computers currently sit on the path to useful materials simulation, what specific material properties could benefit from quantum computational advantage, and the realistic timeline for applying these capabilities to metamaterial design, radar-absorbing materials, and thermal signature management. The interactive demonstration walks through a VQE calculation for a simple material system, illustrating both the potential and the current limitations of the approach.
