Revolution in quantum research: electrical control of molecules!

In the world of quantum technology, exciting developments are currently blooming that not only revolutionize the field, but also significantly expand the possibilities for the future. Fresh progress comes from the University of Jena, where an interdisciplinary team led by Prof. Dr. Winfried Plass has presented groundbreaking results for the control of molecular spin states. According to IDW-Online , the researchers have for the first time demonstrated the direct influence of the spin state of molecules by electrical fields. This technology could significantly advance the development of molecules as quables for quantum computers.

The spin, an alcohol impulse of the electrons, is crucial for storing information in quantum computers. The team of chemists from the universities of Jena and Florence has examined the influences of electric fields for the coupling constant of the spins using electron spin resonance (ESR). In particular, a three -core copper complex was considered, the spins of which strive for an anti -parallel alignment. Here the ligand - an organic connection - plays a central role in coupling the spins.

technological progress in quantum computing

While the Jena researchers explore the molecular level, the project Spinning into another dimension. This is an ambitious project that realizes quantum register by photonic couplings between optical microresonators. Remarkable progress is the successful demonstration of the entanglement of two quantum registers - each with six quBits - over a distance of more than 20 meters. This not only visualizes the scalability of this technology, but also the connection to conventional computer systems seems possible.

The results show a high average quality of over 0.9 in the entangled conditions. In addition, the technology was recognized as particularly suitable for applications in artificial intelligence. The spin-photo-based quantum computer, which works with 12 qubits, delivers an error rate of less than 0.5 % in the one-qubit gate-a respectable value compared to existing superconducting models.

The future of quantum processors

The Spinning project has set the ambitious goal of developing a quantum processor "Made in Germany". This is said to be based on spin-ups in synthetic diamond and could enable the prediction of products of complex quantum chemical reactions. The planned expansion of 10 quBITs to 100 qubits and more shows the ambition to further push the limits of quantum computing.

A striking advantage of this technology is the low cooling requirement, which enables proximity to classic computer systems and thus facilitates integration into existing technologies. As part of the project, the institutions involved - including six universities, two non -profit research institutions and five industrial companies - are planning a pre -competitive development that affects not only the hardware, but also the firmware and software.

With all of these innovative approaches, the region is not only on the right track of playing a leading role in quantum technology. There are promising opportunities in the air that are waiting to be opened up. A look into the future shows that much more can be expected here!
