What is Free 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 Free Quantum Computing software currently available using the table below. This list is updated regularly.

Covalent
Agnostiq
Covalent’s serverless HPC architecture allows you to easily scale jobs from your laptop to your HPC/Cloud. Covalent is a Pythonic workflow tool for computational scientists, AI/ML software engineers, and anyone who needs to run experiments on limited or expensive computing resources including quantum computers, HPC clusters, GPU arrays, and cloud services. Covalent enables a researcher to run computation tasks on an advanced hardware platform – such as a quantum computer or serverless HPC cluster – using a single line of code. The latest release of Covalent includes two new feature sets and three major enhancements. True to its modular nature, Covalent now allows users to define custom pre- and post-hooks to electrons to facilitate various use cases from setting up remote environments (using DepsPip) to running custom functions.Starting Price: Free
