qutip-qtrl 0.1.0

This is the first release of qutip-qtrl, the quantum control package in QuTiP.

The qutip-qtrl package used to be a module qutip.control under QuTiP (Quantum Toolbox in Python). From QuTiP 5.0, the community has decided to decrease the size of the core QuTiP package by reducing the external dependencies, in order to simplify maintenance. Hence a few modules are separated from the core QuTiP and will become QuTiP family packages. They are still maintained by the QuTiP team but hosted under different repositories in the QuTiP organization.

The qutip-qtrl package, QuTiP quantum optimal control, aims at providing advanced tools for the optimal control of quantum devices.

Features

• The cy_grape_unitary optimizer now uses the QuTiP 5 data layer directly and no longer requires Cython. The cy_grape module remains available for compatibility, but also no longer uses Cython.

Bug Fixes

• The grape_unitary_adaptive optimizer previously overwrote the target unitary with the identity. It no longer does this.
