## What it is
QPanda 2 is an open-source quantum computing framework by Origin Quantum for building, running, and optimizing quantum algorithms, with a C++ core and Python bindings (pyqpanda). It includes a quantum virtual machine simulator and serves as the base library for Origin Quantum's toolchain such as QRunes and Qurator.

## Use cases
- simulate quantum circuits on a classical CPU
- build and run quantum algorithms like Grover or QAOA
- create entangled states and measure qubit results
- program quantum computers in Python or C++
- prototype quantum algorithms before running on real hardware
- teach quantum computing with a programming SDK

## When to choose
- you want a high-performance C++ quantum simulator with Python bindings
- you are working in Origin Quantum's ecosystem (QRunes, OriginQ Cloud)
- you need to construct, run, and optimize quantum circuits programmatically

## When to avoid
- you need a hardware-agnostic framework with broad vendor backends like Qiskit or Cirq
- you require the newest Python versions without compiling from source
- you need extensive community plugins beyond the Origin Quantum ecosystem

## Facets
- artifact type: framework
- maturity: active
- function: simulation, sdk, interpreter, developer-tools
- domain: quantum-computing, developer-tools, programming-languages
- platform: windows, cpp, python, cross-platform
- tags: quantum-computing, quantum-simulator, quantum-algorithms, pyqpanda, quantum-development-kit, cpp14, algorithms, linux, macos
