Longxun Quantum

Longxun Quantum (龙讯旷腾) is a Beijing-based quantum software company developing PWmat, a powerful plane-wave pseudopotential software package for quantum mechanical simulations of materials. The company provides computational tools for density functional theory (DFT) calculations, molecular dynamics simulations, and materials property predictions used in semiconductor, battery, and catalyst research. PWmat leverages GPU acceleration for high-performance quantum mechanical calculations, enabling researchers to simulate larger systems and longer timescales than traditional CPU-based approaches. Longxun also operates MCloud, a supercomputing cloud platform for materials simulation. The company serves academic research institutions and industrial R&D departments requiring advanced materials simulation capabilities.

2025 Developments: The company continues to enhance PWmat software capabilities and expand its user base in materials science and chemistry research communities in 2025. Focus remains on improving simulation accuracy and computational efficiency.
