Quantum HRF Tomography
Efficient and Robust Reconstruction of Real-Valued Quantum States using Hadamard Random Forests
Summary
⚡ Fast: Reduces required quantum circuits from exponential to linear in the number of qubits
🎯 Accurate: Achieves 89% fidelity on 10-qubit real states using IBM quantum hardware
🧠 Smart: Uses a random forest over hypercube graphs for efficient sign reconstruction
Introduction
This is the code that accompanies the following paper: arxiv.org/abs/2505.06455
Install
We recommend cloning the repo. and installing locally:
bash
git clone https://github.com/comp-physics/Quantum-HRF-Tomography
cd Quantum-HRF-Tomography
python -m venv qenv
source qenv/bin/activate
pip install -e .
pip install jupyter
To visualize the tree structure, one needs to install Graphviz to enforce the graph layout. For macOS,
bash
brew install graphviz
pip install --global-option=build_ext \
--global-option="-I$(brew --prefix graphviz)/include" \
--global-option="-L$(brew --prefix graphviz)/lib" \
pygraphviz
Please refer to here for more instructions. Then one can use
python
import hadamard_random_forest as hrf
hrf.get_statevector(num_qubits, num_trees, samples, save_tree=True, show_tree=True)
