What is Quantum Computing Software?

Quantum computing software is designed to simulate quantum systems. It enables developers to explore the potential of quantum computing and can be used for a variety of applications such as cryptography, search optimization, materials simulation, machine learning and artificial intelligence. Quantum computers are powered by algorithms that use qubits instead of classical bits which allow them to calculate with a much higher speed than regular computers. The open-source nature of many quantum computing software packages allows anyone who has an interest in this technology to create projects and new algorithms. Compare and read user reviews of the best Quantum Computing software currently available using the table below. This list is updated regularly.

    InQuanto

    InQuanto

    Quantinuum

    Quantum computing offers a path forward to rapid and cost-effective development of new molecules and materials. InQuanto, a state-of-the-art quantum computational chemistry platform, represents a critical step toward this goal. Quantum chemistry aims to accurately describe and predict the fundamental properties of matter and hence is a powerful tool in the design and development of new molecules and materials. However, molecules and materials of industrial relevance are complex and not easy to accurately simulate. Today’s capabilities force a trade to either use highly accurate methods on the smallest-sized systems or use approximating techniques. InQuanto’s modular workflow enables both computational chemists and quantum algorithm developers to easily mix and match the latest quantum algorithms with advanced subroutines and error mitigation techniques to get the best out of today’s quantum platforms.

    Intel Quantum Simulator

    Intel Quantum Simulator

    Intel Quantum Simulator

    It is based on a complete representation of the qubit state but avoids the explicit representation of gates and other quantum operations in terms of matrices. Intel-QS uses the MPI (message-passing-interface) protocol to handle communication between the distributed resources used to store and manipulate quantum states. Intel-QS builds as a shared library which, once linked to the application program, allows to take advantage of the high-performance implementation of circuit simulations. The library can be built on a variety of different systems, from laptops to HPC server systems.
