Quantum technology will change the future! Right now is the time to set the course for quantum technologies and its applications, whereas certain attention focusses on room temperature technologies. QuApps 2021 prepares the definition of the quantum technology roadmap until 2030. QuApps 2021 will be a recurring event to present and discuss relevant applications material properties and process technologies for quantum applications – from the engineering and market point of view. Prominent keynote speakers will provide insights into potential markets and relevant technologies that will or already have reached market maturity. The range of topics extend from quantum applications in various markets such as quantum sensing, processing of quantum materials, metrology or communication to peripheral and enabling technologies. Partners from basic research come together with partners from industry to pave the way of quantum elements to our life, combining new quantum technologies with state of the art solutions in processing, assembly or control.
