+        <p>Another goal of ARTIQ is to streamline and simplify the design flow of quantum physics instrumentation by promoting design reuse through the development of platform-independent, open-source hardware and software.</p>
+
+        <p>Our aim is to provide a control system suitable for the challenges of modern quantum information research, which is based on modular, parameterized and open components that allow physicists to rapidly design and deploy new experiments.</p>
