What is QSpace?

QSpace is an advanced open-source tensor library specifically designed to handle both Abelian and non-Abelian symmetries. Embedded in C++ and interfaced with Matlab, QSpace facilitates quantum symmetry spaces in tensor network states. Its capabilities allow users to exploit a variety of symmetries, including the U(1) and special unitary groups, making it versatile for different operations across symmetries. QSpace's design emphasizes a bottom-up approach, starting from the defining representation and utilizing Clebsch-Gordan coefficient tensors. This approach makes QSpace a powerful tool for developing tensor network algorithms, providing a user-friendly environment while handling complex symmetry details.

Open Source QSpace

The Open Source QSpace project includes a standard and a community edition. The community edition (OSQSpace) is a tailored version of the standard QSpace (QSpace4u) tensor library which is part of our commitment to fostering an open, collaborative environment for scientific exploration and software development. The community edition is distinctively designed to cater to a vibrant community of developers, researchers, and academicians who are deeply invested in the advancement of tensor network algorithms for quantum lattice models.
