About:
Quantum++ is a high-performance, open-source C++ library for quantum computing simulation and research. It provides a comprehensive set of data structures and algorithms for modeling quantum states, gates, and circuits. Its primary value is enabling rapid prototyping and educational exploration of quantum algorithms using standard C++.

Key Features:

Header-only C++ library for easy integration
Efficient simulation of quantum states and gates
Support for quantum circuits and algorithms
Linear algebra backend using Eigen

Use Cases:

Simulating quantum algorithms for research and education
Prototyping quantum circuits before hardware deployment
Teaching quantum computing concepts in C++ environments

Alternatives:

Qiskit – Python-based framework with hardware integration, while Quantum++ is C++ focused for high-performance simulation.
QuEST – C library optimized for GPU acceleration, whereas Quantum++ offers a modern C++ interface and header-only design.
