Best Practices
Circuit Design
Use appropriate qubit types for your topology
Keep circuits modular and reusable
Label measurements with descriptive keys
Validate circuits against device constraints before execution
Simulation
Use state vector simulation for pure states (more efficient)
Use density matrix simulation only when needed (mixed states, noise)
Leverage parameter sweeps instead of individual runs
Monitor memory usage for large systems (2^n grows quickly)
Hardware Execution
Always test on simulators first
Select best qubits using calibration data
Optimize circuits for target hardware gateset
Implement error mitigation for production runs
Store expensive hardware results immediately
Circuit Optimization
Start with high-level built-in transformers
Chain multiple optimizations in sequence
Track depth and gate count reduction
Validate correctness after transformation
Noise Modeling
Use realistic noise models from calibration data
Include all error sources (gate, decoherence, readout)
Characterize before mitigating
Keep circuits shallow to minimize noise accumulation
Experiments
Structure experiments with clear separation (data generation, collection, analysis)
Use ReCirq patterns for reproducibility
Save intermediate results frequently
Parallelize independent tasks
Document thoroughly with metadata
Additional Resources
Common Issues Circuit too deep for hardware:
Use circuit optimization transformers to reduce depth
See transformation.md for optimization techniques
Memory issues with simulation:
Switch from density matrix to state vector simulator
Reduce number of qubits or use stabilizer simulator for Clifford circuits
Device validation errors:
Check qubit connectivity with device.metadata.nx_graph
Decompose gates to device-native gateset
See hardware.md for device-specific compilation
Noisy simulation too slow:
Density matrix simulation is O(2^2n) - consider reducing qubits
Use noise models selectively on critical operations only
See simulation.md for performance optimization
