Hybrid Quantum Software Engineering

Programming and implementation of quantum software

The first industrially relevant applications of quantum computing will likely be hybrid applications. They combine classic software with the implementation of quantum circuits.

At Hannover Messe 2024, Fraunhofer FOKUS will show how hybrid quantum software can be developed using a structured engineering approach. Such quantum software engineering includes methodological approaches and process models for the creation of hybrid applications, quality criteria for their implementation, the development and use of appropriate tools and runtime environments, as well as the operation of the applications. The advantage of this approach is that the software developed is of higher quality and less prone to errors. To support the development of quantum software for industrial applications, Fraunhofer FOKUS has created a powerful and user-friendly tool for programming quantum systems. With the high-level programming language Qrisp, developers can provide efficient and scalable quantum algorithms. The high-level Qrisp code can be compiled down to the quantum circuit level and is, therefore, fully compatible with most of today's physical backends that use quantum circuits.

Using a simple “Hello World” program, visitors can gain an initial insight into a programming language for quantum computers. They learn about quantum effects such as superpositions and entanglement. Together with Fraunhofer IAF, we are also demonstrating a diamond-based qubit that can be optically controlled and read out. This is a promising approach for future system architectures of quantum computers, as diamonds can be operated at room temperature for spin-based quantum computing, resulting in more stable quantum states for more extensive quantum programs and reduced error rates.

6G NeXt powered by 1ClickMetaverse

3D real-time video transmission to VR glasses

Future services and applications, for example in the field of multimedia, will require a speed and reliability for their transmission that today's mobile networks cannot achieve. The 6G NeXt project is creating an infrastructure that enables a new processing speed for data transmission in mobile networks by distributing computing tasks. This scalable, modular infrastructure exceeds the performance of today's 5G networks in terms of intelligence, performance and efficiency. This is made possible by the use of cloud technologies. The computing capacities are allocated based on latency, energy consumption, and costs.

At the Hannover Messe, Fraunhofer FOKUS will be demonstrating the latest developments in the project with the help of 3D real-time video transmission on VR glasses. To enable such a transmission, complex calculations for creating photorealistic, volumetric representations of the participants in a video conference are outsourced to the edge cloud of a 6G network. The 1ClickMetaverse solutions from Fraunhofer FOKUS, which use dynamic split computing and headless rendering approaches, are used for this. They also require extremely low latency, stable transmission and high bit rates, which are made possible by 6G technology.

Modular 5G Nomadic Node  

Highly specialized campus network for precise positioning on construction sites

Earthmoving and infrastructure construction require precision. Construction equipment must operate with a centimeter or even millimeter accuracy. GNSS sensors, for positioning, support construction equipment operators. Correction values are transmitted to all machine control systems in real-time via a 5G campus network to improve the accuracy of the position calculation. At the same time, live data from the construction site is transmitted to management systems for documentation and billing. For that the neutral host approach is used. It is a new and cost-saving option of 5G technology that allows network infrastructure, such as an antenna, to be shared by companies and multiple network operators. The 5G campus network also guarantees data sovereignty for the construction company carrying out the work.

Live video streams from cameras are transmitted via the 5G campus network to check and control the positioning process and for safety monitoring. The flexible use of cameras also simplifies construction site management. For example, personnel can be instructed remotely during technical faults. The cameras can also be operated from a distance (zoom, rotate). Commercially available smartphones with a video transmission app can be used for this purpose. Another app allows site management or security personnel to select and forward individual or multiple video streams.

The 5G network is enabled by the modular 5G Nomadic Node from Fraunhofer FOKUS, the implementation of a blueprint for temporary, reliable, secure networks consisting of building blocks from the CampusOS technology catalog. The hardware and software of the 5G Nomadic Node from Fraunhofer FOKUS is integrated in a robust, transportable server case. The software-based core network Open5GCore ensures a flexible network tailored to the application - even with a satellite connection if required. The 5G Nomadic Node supports radio systems from several providers, including the Open RAN radio systems from CampusOS project partners Fraunhofer HHI and Node-H. TU Berlin is researching Open RAN-based optimization methods. Project partner Topcon Deutschland Positioning integrates the GNSS sensors and the connection to the construction machinery. The video transmission apps come from the company Smart Mobile Labs.
