Measuring tiny magnetic fields, such as those generated by brain waves, enables many new novel opportunities for medical diagnostics and treatment. The research team led by Dr. Jan Jeske at Fraunhofer IAF is working on a globally innovative approach to precise magnetic field measurements: Laser Threshold Magnetometry. The researchers have now combined an NV diamond and a laser diode in a resonator, successfully demonstrating the sensor system with two active media for the first time. This outstanding paper has been published in Science Advances and represents a significant progress in the BMBF-funded research project NeuroQ.

Researchers at Paderborn University have now successfully constructed Europe’s largest sampling-based quantum computer. The ‘PaQS’ (‘Paderborn Quantum Sampler’) was built up as part of the PhoQuant funding initiative by the Federal Ministry of Education and Research (BMBF) by the researchers at Paderborn University with support from Menlo Systems, Fraunhofer IOF Jena and Swabian Instruments. The project is coordinated by Q.ANT, a German company specialising in industrial quantum technologies, and will soon launch a second, cloud-accessible sampling-based quantum computer located at Fraunhofer IOF in Jena. This project, with a funding of around 50 million euros, combines expertise from 13 science and industry partners to put Germany at the international forefront of photonic quantum computing.

Researchers from Saarland University (UdS) have achieved an important breakthrough in Quantum Communication by demonstrating Quantum Entanglement and Teleportation over a 14 km long fiber link, the “Saarbrücken Quantum Communication Fiber Testbed”.

Advancing the key technology of quantum computing: This is the mission of the Competence Center Quantum Computing Baden-Württemberg (KQCBW). The center is now entering the next phase, in which it will build on the successful cooperation projects to date. The continuation of the research and development work of its partners from science and industry is being prepared within a transfer project. Under the leadership of the Fraunhofer IAF and IAO institutes, the KQCBW is further expanding its leading role in application-oriented quantum computing research in order to unlock the application potential of quantum computers for industry.

QuantumDiamonds GmbH, a pioneer in quantum sensing technology, announced the release of the QD m.0, the first commercial quantum device designed for semiconductor chip failure analysis. This advanced system utilizes diamond-based quantum microscopy to deliver unprecedented precision in detecting and localizing faults in integrated circuits, meeting the increasing testing demands for heterogeneous integration in modern semiconductor fabrication.

In the Sequin project, Fraunhofer IPMS is developing a circuit concept as well as the circuit board design, the HDL development of the security orchestrator with the associated firmware basis and driver development and subsequent integration in the project.

In a first for Germany, researchers at the Karlsruhe Institute of Technology (KIT) have shown how so-called tin vacancies in diamonds can be precisely controlled using microwaves. These vacancies have special optical and magnetic properties and can be used as qubits, the smallest computational units for quantum computing and quantum communication. The results are an important step for the development of high-performance quantum computers and secure quantum communications networks. T

In the CiRQus project, we have implemented laser-controlled interactions between a highly-excited circular Rydberg qubit and a second ionic core electron. This achievement advances control of circular Rydberg atoms from the microwave to the optical domain by combining established tools for manipulating trapped ions with neutral atom arrays.

In the “Cluster4Future” QSens of the Universities of Stuttgart and Ulm, scientists, companies and start-ups are researching quantum sensors with a wide range of potential applications. The Federal Ministry of Education and Research is funding QSens for a further three years as part of “Clusters4Future”.

Spintronics uses the spins of electrons to perform logic operations or store information. Ideally, spintronic devices could operate faster and more energy-efficiently than conventional semiconductor devices. However, it is still difficult to create and manipulate spin textures in materials.
