Kernpiler: Compiler Optimization for Quantum Hamiltonian Simulation with Partial Trotterization

Description This artifact contains the core implementation of Kernpiler, a compiler framework for optimizing quantum circuits, and supports full reproducibility of all experimental results presented in the associated paper. The artifact includes all code, data pipelines, and scripts required to regenerate Figures 5–11. System Used for Data Collection NVIDIA A100 GPU with 80GB memory AMD EPYC 9654P 96-core processor x86_64 Linux system Python 3.13.5 Experiments may be computationally intensive, but they are fully parallelizable across multiple devices. Installation Clone or download the repository and navigate to the project directory. Create a virtual environment: python3 -m venv validate source validate/bin/activate Install dependencies: python -m pip install -r requirements.txt Install torch-scatter: python -m pip install --no-cache-dir torch-scatter -f https://data.pyg.org/whl/torch-2.10.0+cu128.html Experiment Workflow All experiment scripts are located in: src/compiler/optimization_passes/experiments Each figure can be reproduced by running its corresponding data collection and graphing scripts: Figure 5exp_gatecount_datacollection.py→ graph using:graph_data_scripts/graph_absolute.py Figure 6exp_partition_scaling_datacollection_o1exp_partition_scaling_datacollection→ graph using:graph_data_scripts/graph_o1_o2_side_by_side.py Figure 7exp_runtime_per_pass.py→ graph using:graph_data_scripts/graph_runtime_per_pass.py Figure 8exp_partition_scaling_datacollectiono1_phoenixFT→ graph using:graph_data_scripts/graph_firstorder_scalingFT.py Figure 9exp_partitionalgvsrandom.py→ graph using:graph_data_scripts/graph_partition_vs_random.py Figure 10exp_scaling_data_rewriteradius.py→ graph using:graph_data_scripts/graph_scalingdata.py Figure 11exp_error_scaling_systemsize.py→ output generated directly (no additional graph script required) Execution Notes All experiments are independent Parallel execution is supported Runtime varies depending on system size and hardware
