A Python application by QxBranch for running Quantum Feature Detectors

Project description


QxBranch’s Quantum Feature Detector (QxQFD) is a Python library providing a configurable class of quantum machine learning functions. It provides a simple interface for using quantum transformations to detect features in data as part of a machine learning application stack, on Rigetti’s QCS.


QxQFD requires the following Python packages:

  • Python 3.6
  • Pyquil 2.0.0
  • numpy
  • matplotlib
  • scikit-learn
  • networkx

QxQFD officially supports Linux 18.04.


QxQFD can be used with a Rigetti Forest QMI, or a local machine running the Forest SDK QVM.

Included with QxQFD are three demonstration notebooks providing examples of the library’s use. They can be found in the ‘demo’ folder. The CIFAR-10 data required for the third notebook can be found at


Complete documentation is available on QxBranch’s website at

At this address you can also find some demonstration iPython notebooks.
