The two companies are working together on the development and industrialization of the first quantum sensor for commercial use. "Our aim is to develop a sensor about the size of a sugar cube that can be used practically anywhere. The extremely cost-effective design of the sensor also helps in this respect. The potential applications this opens up are immense," says Philipp Mirliauntas, CSO of duotec. "We are at the beginning of a new era in measurement technology."

Cooling system-free, working at room temperature, space-saving and cost-effective - these are the key features of the quantum-based magnetometer jointly developed by duotec and Quantum Technologies. "The high detection sensitivity and the wide detection range of current, for example, predestine the quantum sensor for areas of application for which there is currently no adequate solution," explains Arthur Rönisch, CIO of Turck duotec. "The sensor is suitable for use in battery management systems in e-mobility or for current measurement in high-voltage networks, for example. Here, the developed system is characterized by the optical functional principle, which ensures galvanic isolation in the system."

Quantum Technologies focuses on sensitive material and magnetic field detection as well as the processing of diamonds for quantum-based sensor technology, so-called high-density NV centers and their use. duotec is responsible for the industrialization of the sensor for commercial use. Robert Staacke, Managing Director of Quantum Technologies, worked as a research assistant at the University of Leipzig on the subject of quantum sensor technology. He is delighted about the cooperation, in which his company acts as a material and component supplier for the highly sensitive magnetic field sensor, while duotec contributes comprehensive development expertise. "As a start-up founded by employees of Leipzig University, we benefit from duotec's many years of experience. The collaboration makes it easier for us to enter the industrial market, where we can offer a scientifically sound and revolutionary new measurement method."

The sensor does not require cooling and the quantum effects can be evaluated under room temperature conditions. At the same time, the sensitive diamond layers can be used at the highest and lowest temperatures and under the most adverse chemical environmental conditions. Another positive feature is that the sensor already has a miniaturized design - comparable in size to a matchbox - and can therefore be produced cost-effectively. The complete electronics for operating the sensor are contained in this installation space. This sensor does not require additional modules, which are necessary for other solutions in this area. This technical solution is protected by a large number of industrial property rights.
