Your First Steps in Quantum Programming

Environment Setup

Quantum programming uses Python. Make sure you have Python 3.9+ installed.

1. Create an isolated environment so libraries don't conflict.

python -m venv qiskit-env

2. Commands to Activate the virtual environment.

Windows: qiskit-env\Scripts\activate
MacOS/Linux: source qiskit-env/bin/activate

3. Installing Qiskit and Related Quantum Computing Packages

pip install qiskit qiskit-aer qiskit-ibmq-provider

4. You can verify that everything is working by running:

python -c "import qiskit; print(qiskit.__qiskit_version__)"

It should print a dictionary containing versions for Terra, Aer, Ignis, etc. If you see an error, double‑check that your virtual environment is activated.

Optionally, create a free IBM Quantum account at quantum-computing.ibm.com and run from qiskit_ibmq import IBMQ; IBMQ.save_account('TOKEN') to store your API key.

Now you’re ready to write your first circuit.
