What is HDH?

HDH (Hybrid Dependency Hypergraph) is an intermediate directed hypergraph-based representation designed to encode the dependecies arising in any quantum workload. It provides a unified structure that makes it easier to:

  • Translate quantum programs (e.g., a circuit or a mbqc pattern) into a unified hypergraph format
  • Analyze and visualize the logical and temporal dependencies within a computation
  • Partition workloads across devices, taking into account hardware and network constraints

Current Capabilities

  • Qiskit, Braket, Cirq and Pennylane circuit mappings to HDHs
  • OpenQASM 2.0 file parsing
  • Model-specific abstractions for:
    • Quantum Circuits
    • Measurement-Based Quantum Computing (MBQC)
    • Quantum Walks
    • Quantum Cellular Automata (QCA)
  • Capability to partition HDHs and evaluate partitions

Installation

pip install hdh

Quickstart

From Qiskit

from qiskit import QuantumCircuit
from hdh.converters import from_qiskit
from hdh.visualize import plot_hdh

qc = QuantumCircuit(2)
qc.h(0)
qc.cx(0, 1)

hdh = from_qiskit(qc)

plot_hdh(hdh)

From QASM file

from hdh.converters import from_qasm
from hdh.visualize import plot_hdh

qasm_path = os.path.join(os.path.dirname(__file__), 'test_qasm_file.qasm')
hdh = from_qasm('file', qasm_path)

plot_hdh(hdh)

Tests and Demos

All tests are under tests/ and can be run with:

pytest
