New open source Python module for quantum optimal control in QuTiP
Source:
QuTiP users (Google) Group
The quantum control group at Aberystwyth University have developed a Python module for quantum optimal control. The module has been incorporated into QuTiP (Quantum Toolbox in Python) and is now part of the official release 3.1.0, which was announced on 1 Jan 2015. The module provides a method for determining control pulses for quantum systems via GRAPE, that is easy to configure, and runs on a free-to-use, open, and scalable platform. Originally based on the DYNAMO MATLAB package (https://quantumcontrol.eu/content/dynamo-package) it has now been extended to support unitary, Lindbladian and Symplectic dynamics, all with exact gradients. The main processing is completed using a well established implementation of the L-BFGS-B algorithm within SciPy, that is developed in Fortran, and is hence very efficient. For further information see the official QuTiP 3.1.0 release statement:
