qubit-mapper

# Qubit Mapper ## Purpose Provides expert guidance on mapping logical qubits to physical hardware while respecting connectivity constraints and minimizing SWAP overhead. ## Capabilities - Initial qubit placement - SWAP gate insertion - Routing optimization algorithms - Topology-aware compilation - Noise-aware placement - Heavy-hex and grid topology support - Dynamic circuit routing - Parallel SWAP optimization ## Usage Guidelines 1. **Topology Analysis**: Understand target hardware connectivity graph 2. **Initial Placement**: Use heuristics for initial logical-physical mapping 3. **Routing**: Insert SWAPs to enable non-native interactions 4. **Optimization**: Minimize SWAP count and circuit depth 5. **Noise Consideration**: Prefer high-fidelity qubits and links ## Tools/Libraries - Qiskit - pytket (t|ket>) - Cirq - BQSKit - NetworkX
