Quimb Tensor Network

Purpose

Provides expert guidance on tensor network simulations for quantum many-body systems, including MPS, DMRG, and entanglement analysis.

Capabilities

• MPS and DMRG calculations
• TEBD time evolution
• Entanglement entropy computation
• Quantum master equation solving
• Open quantum systems dynamics
• GPU-accelerated contractions

Usage Guidelines

1. State Representation: Use MPS for one-dimensional systems
2. Ground States: Run DMRG for ground state calculations
3. Time Evolution: Use TEBD for dynamics
4. Entanglement: Calculate entanglement entropy and spectra
5. Open Systems: Model dissipative quantum systems
