EuroHPC JU has signed agreements with LuxProvide (Luxembourg) & SURF (Netherlands) to host & operate two new quantum computers. The procurement of these systems will start early next year driving Europe's leadership in quantum computing technologies.

Lower cooling requirements, longer operating times, lower error rates: Quantum computers based on spin photons and diamond promise significant advantages over competing quantum computing technologies. The consortium of the BMBF project SPINNING coordinated by Fraunhofer IAF has succeeded in decisively advancing the development of spin-photon-based quantum computers. On October 22 and 23, 2024, the partners presented the interim project results at the mid-term meeting of the BMBF funding measure Quantum Computer Demonstration Setups in Berlin.

Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron spin state of these colour centres. However, the spin states have to be read out optically, which is often experimentally complex. Now, a team at HZB has developed an elegant method using a photo voltage to detect the individual and local spin states of these defects. This could lead to a much more compact design of quantum sensors.

A team of Rice University researchers reported the first direct observation of a surprising quantum phenomenon predicted over half a century ago, opening pathways for revolutionary applications in quantum computing, communication and sensing.

Nuclear spins in a crystal can be detected and manipulated through their interactions with the more accessible electron spin of a neighboring crystal defect. This strategy has enabled nanoscale magnetic resonance imaging and other quantum applications. But a long-standing challenge has been to target a specific nuclear spin, while protecting the delicate quantum nature of the electron spin. Important progress on this challenge has now been achieved by two teams at the Delft University of Technology in the Netherlands.

In the new study, the team formulated a quantum algorithm (a set of computer instructions) that can be used in theory to find low-energy states—what physicists call local minima—of any material. Their study theoretically proves that the algorithm will perform much better than its classical counterparts.

SaxonQ, developer of the first mobile quantum computer, and Quantum Machines, the leading provider of advanced hybrid quantum-classical control solutions, announced today a milestone demonstration of real-time quantum computing on SaxonQ’s mobile quantum computer at Hannover Messe 2025. The live demonstrations included a of H2 energy levels and basic real-time image recognition, marking the first time anyone has shown such applications running on a portable room-temperature quantum computer publicly, demonstrate the potential of mobile quantum computing outside laboratory conditions.

A groundbreaking study from the Technion-Israel Institute of Technology unveils a newly discovered form of quantum entanglement in the total angular momentum of photons confined in nanoscale structures – just a thousandth the width of a human hair. This discovery could play a key role in the future miniaturization of quantum communication and computing components.

A quantum science and engineering graduate student at the University of Chicago’s Pritzker School of Molecular Engineering, Menon and his colleagues in the lab of Hannes Bernien discovered how to combine two powerful technologies – trapped atom arrays and photonic devices – to yield advanced systems for quantum computing.
