▶️ Running quantum circuits in VS Code (no Anaconda/Jupyter required)

You can run the example circuits directly inside VS Code using the integrated terminal. Jupyter/Anaconda are optional – not required.

Prerequisites

VS Code extensions: Python (Microsoft) and Pylance
Python 3.9–3.12 installed and on PATH

Python setup (recommended)

Install a trusted, minimal set of packages in a virtual environment:

# 1) Create & activate a venv (Windows PowerShell)
python -m venv .venv
. .venv/Scripts/Activate.ps1

# 2) Install packages
pip install --upgrade pip
pip install "qiskit>=1.0,<2.0" "qiskit-aer>=0.14,<1.0" \
            "cirq-core>=1.2,<2.0" "pennylane>=0.36,<0.40"

Then in VS Code:

Select Interpreter: Ctrl+Shift+P → “Python: Select Interpreter” → choose .venv.
Open a Python file with a snippet (e.g., Qiskit Bell state) and press the Play (Run) button or run in terminal:

python your_script.py

Notes

Local simulators: use qiskit-aer (Qiskit) or built‑in Cirq simulators.
Real hardware requires provider accounts/tokens (outside the scope of this beta).

JavaScript/TypeScript (optional)

Snippets are provided for quick prototyping. To execute Node projects:

Install Node.js 18+ (LTS) and npm.
Initialize a project and add dependencies you need (e.g., simulators):

npm init -y
# add your preferred simulation libs or tooling here

This beta focuses on Python execution; JS/TS templates are for reference and editor assistance.
