Qiskit Dynamics is an open-source project for building, transforming, and solving time-dependent quantum systems in Qiskit.

The goal of Qiskit Dynamics is to provide access to different numerical methods for solving differential equations, and to automate common processes typically performed by hand, e.g. applying frame transformations or rotating wave approximations to system and control Hamiltonians.

Qiskit Dynamics can be configured to use either NumPy or JAX as the backend for array operations. NumPy is the default, and JAX is an optional dependency. JAX provides just-in-time compilation, automatic differentiation, and GPU execution, and therefore is well-suited to tasks involving repeated evaluation of functions with different parameters; E.g. simulating a model of a quantum system over a range of parameter values, or optimizing the parameters of control sequence.

Reference documentation may be found here, including tutorials, user guide, and API reference.

Qiskit Dynamics may be installed using pip via:

pip install qiskit-dynamics

Additionally, Qiskit Dynamics may be installed simultaneously with the CPU version of JAX via:

pip install "qiskit-dynamics[jax]"

Installing JAX with GPU support must be done manually, for instructions refer to the JAX installation guide.
