Quantum Computing Frameworks

Quantum computing frameworks are software platforms that enable developers, researchers, and scientists to design, simulate, and execute quantum algorithms on quantum hardware or simulators. These frameworks provide high-level abstractions, libraries, and tools to work with quantum circuits, gates, and qubits without needing to manage low-level hardware details.

Below is an overview of the most prominent quantum computing frameworks:

Qiskit (IBM)

Language: Python
Key Features:
Open-source SDK developed by IBM.
Supports circuit design, simulation, and execution on IBM’s real quantum processors via IBM Quantum Experience.
Includes modules for optimization (Qiskit Optimization), machine learning (Qiskit Machine Learning), and chemistry (Qiskit Nature).
Extensive documentation, tutorials, and active community.
Hardware Access: IBM Quantum systems (via cloud).

Cirq (Google)

Language: Python
Key Features:
Developed by Google Quantum AI.
Focused on near-term quantum algorithms and noisy intermediate-scale quantum (NISQ) devices.
Allows fine-grained control over quantum gates and timing.
Integrates with TensorFlow Quantum for hybrid quantum-classical machine learning.
Hardware Access: Supports Google’s Sycamore processor and other simulators.

PennyLane (Xanadu)

Language: Python
Key Features:
Designed for quantum machine learning and differentiable programming.
Supports photonic quantum computing (Xanadu’s hardware) as well as gate-based backends (IBM, Rigetti, etc.).
Integrates with PyTorch and TensorFlow for automatic differentiation.
Emphasizes variational quantum algorithms and parameterized circuits.
Hardware Access: Xanadu’s photonic chips (via cloud), plus simulators and third-party devices.
