Open Controls

View on Github

Open Controls is an open-source Python package that makes it easy to create and deploy established error-robust quantum control protocols from the open literature. The aim of the package is to be the most comprehensive library of published and tested quantum control techniques developed by the community, with easy to use export functions allowing users to deploy these controls on:

  • Custom quantum hardware
  • Publicly available cloud quantum computers
  • The Q-CTRL product suite

Anyone interested in quantum control is welcome to
contribute to this project

Getting Started

$ pip install qctrl-open-controls
Example of using it in a console:
>>> from qctrlopencontrols import new_predefined_dds
>>> cpmg_4 = new_predefined_dds(
>>> print(cpmg_4)
Duration = 1e-05
Offsets = [0.0,0.125,0.375,0.625,0.875,1.0] x 1e-05
Rabi Rotations = [0.0,1.0,1.0,1.0,1.0,0.0] x pi
Azimuthal Angles = [0.0,0.5,0.5,0.5,0.5,0.0] x pi
Detuning Rotations = [0.0,0.0,0.0,0.0,0.0,0.0] x pi
