Qiskit Dynamics
What Qiskit Dynamics is
Qiskit Dynamics is a free, open-source Python package for building, transforming, and solving time-dependent quantum systems in Qiskit. It provides numerical methods for differential equations and automates operations such as frame transformations and rotating wave approximations. The systems module offers higher-level interfaces for constructing abstract quantum-system models and performing calculations. NumPy is the default array backend. JAX is optional for just-in-time compilation, automatic differentiation, and GPU execution. DynamicsBackend supplies a BackendV2 interface for pulse-level simulation and can simulate Qiskit Pulse schedules. Installation uses pip, with an optional extra for the CPU version of JAX. The package is licensed under Apache License 2.0 and is classified for developers and science or research audiences. Version 0.6.0 requires Qiskit 1.3 or earlier, and DynamicsBackend works only with Qiskit Experiments 0.8 releases. Maintainers say the repository is no longer actively maintained and call 0.6.0 the last release for the foreseeable future.
Who it suits
It is aimed at developers and science or research users building quantum-system models or pulse simulations in Qiskit. Users should be comfortable managing its stated Qiskit compatibility requirements.
