Extra-fast quantum computer for Stuttgart
The race for the future of quantum computing is in full swing internationally. Research is also being carried out in Baden-Württemberg. A project at the University of Stuttgart is currently testing a new idea.
Stuttgart (dpa/lsw) - A research group at the University of Stuttgart wants to build a new, very fast quantum computer by 2025. In contrast to the well-known quantum computers from companies such as IBM or Microsoft, the new quantum computer works with individual atoms that can be controlled with laser light, said Tilman Pfau, the coordinator of the "QRydDemo" project. "Our project, if I may say so briefly, aims to process quantum information very quickly and to run the algorithms quickly," he explained.
The project was launched more than two years ago and will run until January 31, 2025, with funding of around 9 million euros from the Federal Ministry of Education and Research. The project partners are the University of Stuttgart, the University of Ulm and the company Toptica Photonics.
Quantum computers can calculate much faster than conventional computers. Different technologies can be behind this. Research is currently being carried out to determine which technology is particularly suitable. According to current knowledge, the most promising physical systems are superconductors, ion traps and atom traps for neutral atoms, according to the "QRydDemo" project. The project is working on a so-called neutral atom platform.
According to Florian Meinert, one of the project's lead researchers, the basic building blocks of a quantum computer are the so-called qubits. The project in Stuttgart is aiming for a quantum computer with 500 qubits, he explained. "We can currently make a few dozen, but the basic methods we use are relatively easy to scale up."
