About Pasqal

PASQAL designs and develops Quantum Processing Units (QPUs) and associated software tools.
Our innovative technology enables us to address use cases that are currently beyond the reach of the most powerful supercomputers; these cases can concern industrial application challenges as well as fundamental science needs.
In addition to the exceptional computing power they provide, QPUs are highly energy efficient and will contribute to a significant reduction in the carbon footprint of the HPC industry. 

Overview

PasqOS is the software operating Pasqal's bleeding edge Quantum Processing Units (QPU). It is a fairly complex software that interacts with a lot of hardware written mostly in Python and mixes a lot of technologies. It comes with a web interface and a set of APIs for cloud clients. The web interface provides job management and health monitoring for the QPU.
