Divi
Generate, parallelize, and execute quantum programs at scale.
Divi is a Python library by Qoro Quantum for building and running quantum programs at scale. It handles circuit generation, job parallelization, and cloud execution — with built-in support for variational algorithms, custom workflows, and more — so you can focus on the quantum problem, not the plumbing.
[!IMPORTANT] Divi is under active development. Expect breaking changes between minor versions.
⚡ Quick Start
pip install qoro-divi
Nightly Builds
To install the latest development build (published daily from main):
pip install qoro-divi --pre
Run a VQE energy minimization in a few lines:
import numpy as np
import pennylane as qml
from divi.qprog import VQE, HartreeFockAnsatz
from divi.backends import MaestroSimulator
from divi.qprog.optimizers import ScipyOptimizer, ScipyMethod
# Define an H₂ molecule
molecule = qml.qchem.Molecule(
symbols=["H", "H"],
coordinates=np.array([(0, 0, 0), (0, 0, 0.5)]),
)
vqe = VQE(
molecule=molecule,
ansatz=HartreeFockAnsatz(),
n_layers=2,
backend=MaestroSimulator(shots=5000),
optimizer=ScipyOptimizer(method=ScipyMethod.COBYLA),
seed=42,
)
vqe.run()
print(f"Ground state energy: {vqe.best_loss:.6f}")
🌐 Cloud Execution with Qoro Service
Run the same programs on Qoro's cloud platform with tensor-network simulators — no code changes needed:
from divi.backends import QoroService
service = QoroService() # reads QORO_API_KEY from .env or environment
vqe = VQE(molecule=molecule, backend=service)
vqe.run()
