scikit-quant is an aggregator package to improve interoperability between quantum computing software packages. Our first focus in on classical optimizers, making the state-of-the art from the Applied Math community available in Python for use in quantum computing.

Installation
pip install sckit-quant
Usage
Basic example (component interfaces for standard quantum programming frameworks and for SciPy are available as well):
import numpy as np
from skquant.opt import minimize
# some interesting objective function to minimize
def objective_function(x):
fv = np.inner(x, x)
fv *= 1 + 0.1*np.sin(10*(x[0]+x[1]))
return np.random.normal(fv, 0.01)
# create a numpy array of bounds, one (low, high) for each parameter
bounds = np.array([[-1, 1], [-1, 1]], dtype=float)
# budget (number of calls, assuming 1 count per call)
budget = 40
# initial values for all parameters
x0 = np.array([0.5, 0.5])
# method can be ImFil, SnobFit, Orbit, NOMAD, or Bobyqa
result, history = \
minimize(objective_function, x0, bounds, budget, method='imfil')
