-## Safety Features - -### Override Warnings - -The factory warns when you override default mappings: - -```python -factory = GeneralNoiseFactory() -factory.add_mapping("p1", "with_p2_probability", float) -# UserWarning: Overriding default mapping for 'p1': -# 'with_p1_probability' -> 'with_p2_probability' -``` - -### Mapping Visualization - -View current mappings with visual indicators: - -```python -factory.show_mappings() -# Current Parameter Mappings: -# ================================================================================ -# Configuration Key → Builder Method Description -# -------------------------------------------------------------------------------- -# *p1 → with_p2_probability Single-qubit gate error -# p2 → with_p2_probability Two-qubit gate error -# ... -# * = Overridden default mapping -``` - -### Strict Mode Validation - -By default, unknown keys raise errors: - -```python -# Strict mode (default) -factory.create_from_dict({"unknown_key": 123}) # Raises ValueError - -# Non-strict mode -factory.create_from_dict({"unknown_key": 123}, strict=False) # Ignores unknown keys -``` - -## Customization - -### Starting Without Defaults - -Create an empty factory for complete control: - -```python -# Three equivalent ways to create an empty factory -factory = GeneralNoiseFactory(use_defaults=False) -factory = GeneralNoiseFactory.empty() -``` - -### Adding Custom Mappings - -```python -factory = GeneralNoiseFactory.empty() - -# Add custom mappings with domain-specific terminology -factory.add_mapping( - "single_gate_error", - "with_p1_probability", - float, - "Error rate for single-qubit gates", -) -factory.add_mapping( - "two_gate_error", "with_p2_probability", float, "Error rate for two-qubit gates" -) -factory.add_mapping( - "readout_error", "with_meas_0_probability", float, "Readout error probability" -) - -# Use domain-specific configuration -config = { - "single_gate_error": 0.001, - "two_gate_error": 0.01, - "readout_error": 0.002, -} -noise = factory.create_from_dict(config) -``` - -### Removing Unwanted Mappings - -Remove mappings you don't need: - -```python -factory = GeneralNoiseFactory() - -# Remove mappings if not needed -factory.remove_mapping("p1_average") # Remove average probability -factory.remove_mapping("p2_average") # Remove average probability -``` - -### Custom Type Converters - -Add mappings with custom value conversion: - -```python -# Convert percentage to probability -def percent_to_prob(percent): - return percent / 100.0 - - -factory.add_mapping( - "p1_percent", "with_p1_probability", percent_to_prob, "P1 error as percentage" -) - -# Use percentage in config -config = {"p1_percent": 0.1} # 0.1% = 0.001 probability -``` - -## Advanced Examples - -### Ion Trap Noise Model - -Create a specialized factory for ion trap quantum computers: - -```python -# Create ion trap specific factory -factory = GeneralNoiseFactory.empty() - -# Add ion trap terminology -factory.add_mapping( - "state_prep_error", "with_prep_probability", float, "State preparation infidelity" -) -factory.add_mapping( - "single_qubit_error", "with_p1_probability", float, "Single-qubit gate infidelity" -) -factory.add_mapping( - "two_qubit_error", "with_p2_probability", float, "Two-qubit gate infidelity" -) -factory.add_mapping( - "dark_count", "with_meas_0_probability", float, "Dark count probability" -) -factory.add_mapping( - "detection_error", "with_meas_1_probability", float, "Bright state detection error" -) -factory.add_mapping( - "motional_heating", - "with_scale", - lambda x: 1.0 + x * 0.01, # Convert to scale factor - "Motional heating rate", -) - -# Typical ion trap parameters -config = { - "state_prep_error": 0.001, - "single_qubit_error": 0.0001, # Very good single-qubit gates - "two_qubit_error": 0.003, # Main error source -

-```python -config = { - # Global settings - "seed": 42, - "scale": 1.2, # Scale all errors by 20% - # Make specific gates noiseless - "noiseless_gates": ["H", "S", "T"], - # State preparation - "p_prep": 0.0005, - # Single-qubit gates with Pauli distribution - "p1_average": 0.001, - "p1_pauli_model": { - "X": 0.5, # 50% X errors - "Y": 0.3, # 30% Y errors - "Z": 0.2, # 20% Z errors - }, - # Two-qubit gates - "p2_average": 0.008, - "p2_pauli_model": { - "IX": 0.25, - "XI": 0.25, - "XX": 0.5, - }, - # Asymmetric measurement errors - "p_meas_0": 0.002, # 0->1 flip - "p_meas_1": 0.005, # 1->0 flip (higher) -} - -noise = factory.create_from_dict(config) -``` - -### Factory with Defaults - -Set factory-wide default values: - -```python -factory = GeneralNoiseFactory() - -# Set common defaults -factory.set_default("seed", 42) -factory.set_default("p1", 0.001) -factory.set_default("p2", 0.01) -factory.set_default("p_meas_0", 0.002) -factory.set_default("p_meas_1", 0.002) - -# Empty config uses all defaults -noise1 = factory.create_from_dict({}) - -# Override specific values -noise2 = factory.create_from_dict( - { - "p2": 0.005, # Override two-qubit error - "scale": 0.5, # Scale down all errors by 50% - } -) -``` - -## Validation - -Validate configurations before use: - -```python -factory = GeneralNoiseFactory() - -config = { - "p1": "not_a_number", # Type error - "unknown_key": 123, # Unknown key - "p2": 0.01, # Valid -} - -errors = factory.validate_config(config) -print(errors) -# { -# 'p1': "could not convert string to float: 'not_a_number'", -# 'unknown_keys': "Unknown keys: {'unknown_key'}" -# } -``` - -## Best Practices - -1. **Use descriptive keys**: When creating custom factories, use clear, descriptive parameter names that match your domain. - -2. **Document your mappings**: Always provide descriptions when adding custom mappings. - -3. **Validate early**: Use `validate_config()` before creating noise models in production code. - -4. **Remove confusing aliases**: If the default aliases are confusing for your use case, remove them and keep only the primary keys. - -5. **Version your configurations**: Store noise configurations in version-controlled JSON files for reproducibility. - -6. **Use type converters**: Add appropriate converters (e.g., percentage to probability) to make configurations more intuitive. - -## Integration with Existing Code - -The factory integrates seamlessly with PECOS simulation APIs: - -```python -from pecos.rslib import qasm_sim, GeneralNoiseFactory - -# Create noise from configuration -factory = GeneralNoiseFactory() -noise = factory.create_from_dict( - { - "seed": 42, - "p1": 0.001, - "p2": 0.01, - } -) - -# Use with builder pattern -sim = qasm_sim(qasm).noise(noise).workers(4).build() -results = sim.run(1000) - -# Or direct execution -results = qasm_sim(qasm).noise(noise).run(1000) -``` -

This means potential breaking changes might occur between MINOR increments, such +as moving from versions 0.1.0 to 0.2.0. + +All Python packages and all Rust crates will have the same version amongst their +respective languages; however, Python and Rust versioning will differ. + +## Latest Development + +Stay updated with the latest developments on the +[PECOS Development branch](https://quantum-pecos.readthedocs.io/en/development/). + +## Installation + +### Python Package + +To install the main Python package for general usage: + +```sh +pip install quantum-pecos +``` + +This will install both `quantum-pecos` and its dependency `pecos-rslib`. + +For optional dependencies: + +```sh +pip install quantum-pecos[all] +``` + +**NOTE:** The `quantum-pecos` package is imported like: `import pecos` and not `import quantum_pecos`. + +**NOTE:** To install pre-releases (the latest development code) from pypi you may have to specify the version you are +interested like so (e.g., for version `0.6.0.dev5`): +```sh +pip install quantum-pecos==0.6.0.dev5 +``` + +**NOTE:** Certain simulators have special requirements and are not installed by the command above. Installation instructions for +these are provided [here](#simulators-with-special-requirements). + + +### Rust Crates + +To use PECOS in your Rust project, add the following to your `Cargo.toml`: + +```toml +[dependencies] +pecos = "0.x.x" # Replace with the latest version +``` + +#### Optional Dependencies + +- **LLVM version 14**: Required for LLVM IR execution support (optional) + + PECOS provides an automated installer or you can install manually: + + ```sh + # Quick setup with automated installer (recommended): + cargo run -p pecos-llvm-utils --bin pecos-llvm -- install + cargo build + ``` + + The installer automatically configures PECOS after installation. + + For detailed LLVM installation instructions for all platforms (macOS, Linux, Windows), see the [**Getting Started Guide**](docs/user-guide/getting-started.md#llvm-for-qis-support). + + For full development environment setup, see the [**Development Setup Guide**](docs/development/DEVELOPMENT.md). + + **Building without LLVM:** If you don't need LLVM IR support: + ```sh + cargo build --no-default-features + ``` + +### Julia Package (Experimental) + +PECOS also provides experimental Julia bindings. To use the Julia package from the development branch: + +```julia +using Pkg +Pkg.add(url="https://github.com/PECOS-packages/PECOS#dev", subdir="julia/PECOS.jl") +``` + +Then you can use it: + +```julia +using PECOS +println(pecos_version()) # Prints PECOS version +``` + +**Note**: The Julia package requires the Rust FFI library to be built. Currently, you need to build it locally: +1. Clone the repository +2. Build the FFI library: `cd julia/pecos-julia-ffi && cargo build --release` +3. Add the package locally: `Pkg.develop(path="julia/PECOS.jl")` + +## Development Setup + +If you are interested in editing or developing the code in this project, see this +[development documentation](docs/development/DEVELOPMENT.md) to get started. + +## Simulators with special requirements + +Certain simulators from `pecos.simulators` require external packages that are not installed by `pip install .[all]`. + +### GPU-Accelerated Simulators (CuStateVec and MPS) + +- **`CuStateVec`** and **`MPS`** require: + - Linux machine with NVIDIA GPU (Compute Capability 7.0+) + - CUDA Toolkit 13 or 12 (system-level installation) + - Python packages: `cupy-cuda13x`, `cuquantum-python-cu13`, `pytket-cutensornet` + +**Installation:** See the comprehensive [CUDA Setup Guide](docs/user-guide/cuda-setup.md) for detailed step-by-step instructions. + +**Quick install** (after installing CUDA Toolkit): +```bash +uv pip install quantum-pecos[cuda] + +# For development with CUDA support: +make build-cuda # Build with CUDA +make devc # Full dev cycle (clean + build-cuda + test) +make devcl # Dev cycle + linting +``` + +**Note:** When using `uv` or `pip`, install CUDA Toolkit via system package manager (e.g., `sudo apt install cuda-toolkit-13`), then install Python packages. Conda environments may conflict with `uv`/`venv` workflows. + +## Uninstall + +To uninstall: + +```sh +pip uninstall quantum-pecos +``` + +## Citing + +For publications utilizing PECOS, kindly cite PECOS such as: + +```bibtex +@misc{pecos, + author={Ciar\'{a}n Ryan-Anderson}, + title={PECOS: Performance Estimator of Codes On Surfaces}, + publisher = {GitHub}, + journal = {GitHub repository}, + howpublished={\url{https://github.com/PECOS-packages/PECOS}}, + URL = {https://github.com/PECOS-packages/PECOS}, + year={2018} +} +``` +And/or the PhD thesis PECOS was first described in: +```bibtex +@phdthesis{crathesis, + author={Ciar\'{a}n Ryan-Anderson}, + school = {University of New Mexico}, + title={Quantum Algorithms, Architecture, and Error Correction}, + journal={arXiv:1812.04735}, + URL = {https://digitalrepository.unm.edu/phyc_etds/203}, + year={2018} +} +``` + +You can also use the [Zenodo DOI](https://zenodo.org/records/13700104), which would result in a bibtex like: +```bibtex +@software{pecos_[year], + author = {Ciar\'{a}n Ryan-Anderson}, + title = {PECOS-packages/PECOS: [version]]}, + month = [month], + year = [year], + publisher = {Zenodo}, + version = {[version]]}, + doi = {10.5281/zenodo.13700104}, + url = {https://doi.org/10.5281/zenodo.13700104} +} +``` + + +## License + +This project is licensed under the Apache-2.0 License -
