At the forefront of quantum innovation, a new research group at the University of Stuttgart is poised to revolutionize the fields of quantum computing and communication. Led by physicist Dr. Stephan Welte, the Emmy Noether junior research group “Quantum Network Nodes” has secured 1.9 million euros in funding to explore the uncharted territories of qubits, the fundamental units of quantum information. By harnessing the power of atoms as qubits, Welte’s team aims to develop a secure and tap-proof quantum internet, where information can be transmitted with unprecedented speed and security.
Quantum Computing and Communication: A New Era with Emmy Noether Group
The University of Stuttgart has launched a new Emmy Noether junior research group, “Quantum Network Nodes,” led by physicist Dr. Stephan Welte. This group focuses on researching quantum computing and quantum communication, with a funding of 1.9 million euros acquired for the project. The research group is based at the 5th Institute of Physics and is part of the Center for Integrated Quantum Science and Technology (IQST), which brings together leading groups in quantum computing and quantum communication.
The University of Stuttgart provides an ideal environment for this research, combining experimental and theoretical expertise. Dr. Welte’s team is researching computing and information transfer using qubits, the smallest units of information in quantum computers and networks. By connecting multiple quantum computers through suitable network interfaces, a secure and tap-proof quantum internet can be established.
The team uses atoms as qubits, positioning and addressing them individually in a highly controlled manner between two highly reflective mirrors. The experiment takes place in a vacuum at extremely low temperatures, using laser light to precisely control the atomic qubits. The acquisition of highly efficient detectors has been made possible by Emmy Noether funding.
Building a Quantum Computer and Network
Dr. Welte’s team is building a quantum computer that can be connected to other quantum computers via a network. Qubits are used to perform certain tasks faster and transmit information securely. By connecting multiple quantum computers, a secure and tap-proof quantum internet can be established. The experiment involves using atoms as qubits, which emit individual photons that can be measured individually using highly efficient detectors.
The team uses laser light, or “optical tweezers,” to precisely control the atomic qubits between the two mirrors. A laser beam is shaped in such a way that it traps individual atoms in the desired positions. The development of the research group is progressing rapidly, with plans to expand the team and offer a broad range of tasks, including optics, electronics design, and programming.
Expanding Research Capabilities
The Emmy Noether funding will enable Dr. Welte’s team to expand its personnel and technical equipment. The team currently consists of two doctoral students, one Master’s student, one Bachelor’s student, and a student assistant. Plans are underway to add a postdoctoral position and a third doctoral position, with open projects for Bachelor’s and Master’s theses.
Dr. Welte’s research focuses on quantum computing and quantum internet, building on his experience in quantum photonics. He has acquired funding from the Carl Zeiss Foundation for his junior research group on quantum photonics at the University of Stuttgart. The Emmy Noether Program provides exceptionally qualified young researchers with the opportunity to qualify for a university professorship by independently leading a junior research group for six years.
Quantum Network Nodes: A Key Component
The “Quantum Network Nodes” research group is a key component in the development of quantum computing and communication. By building a quantum computer that can be connected to other quantum computers via a network, Dr. Welte’s team is paving the way for a secure and tap-proof quantum internet. The experiment involves using atoms as qubits, which emit individual photons that can be measured individually using highly efficient detectors.
The development of quantum network nodes is crucial in establishing a reliable and efficient quantum communication system. Dr. Welte’s research group is at the forefront of this development, pushing the boundaries of what is possible with quantum computing and communication.
