Crate kana 

Kana — Quantum mechanics simulation for AGNOS

Sanskrit: कण (kana) — particle, atom

Provides quantum state vectors, Hilbert spaces, unitary operators, entanglement simulation, quantum circuit primitives, and time evolution. Built on hisab for complex linear algebra (via the hisab-bridge feature).

Modules

• state — State vectors, kets/bras, measurement, Bloch sphere
• operator — Unitary operators, Pauli/rotation gates, decompositions
• entanglement — Density matrices, entanglement measures, noise channels
• circuit — Quantum circuits, gate optimization, algorithms (Grover, QFT, VQE)
• safe — Ownership-based circuit builder (compile-time no-cloning)
• dynamics — Time evolution (Schrodinger, Lindblad master equation)
• [bridge] — Hisab interop (feature-gated)
• [parallel] — Rayon-parallelized operations (feature-gated)
• error — Error types
