Qiskit is an open-source SDK for working with quantum computers at the level of circuits, algorithms, and application modules.
Qiskit is made up of elements that work together to enable quantum computing. This is a simple meta-package to install the elements of Qiskit altogether.
The best way of installing qiskit is by using pip:
$ pip install qiskitSee install Qiskit for detailed instructions, how to use virtual environments, and build from source standalone versions of the individual Qiskit elements and components.
The Qiskit project used to be made up of many components. However, in the future the Qiskit metapackage will only install Qiskit Terra:
| Build | Version | Contribute |
|---|---|---|
| Qiskit Terra |  |
 |
For the time being, two other packages are installed, but these components will be removed from the metapackage in a future release. |
||
| Build | Version | Contribute |
|---|---|---|
| Qiskit Aer | ||
| Qiskit IBM Quantum Provider | ||
These components are part of the Qiskit ecosystem but are built on top of
qiskit and are not installed by default with the meta-package. You can either
install them manually, as an optional extra
(ie pip install "qiskit[finance,experiments]"), or all together with
pip install "qiskit[all]".
| Build | Version | Contribute |
|---|---|---|
| Qiskit Optimization |  |

| Qiskit Finance |  |
 |
| Qiskit Machine Learning |  |
 |
| Qiskit Nature |  |

| Qiskit Experiments |  |

If you are interested in using quantum services (i.e. using a real quantum computer, not a simulator) you can look at the Qiskit Partners program for partner organizations that have provider packages available for their offerings:
