Targeted control of qubits

The development of quantum computers has greatly accelerated in recent years, with the first systems being already available. But they still need further optimizations. Quantum computers are believed to be the key to a wide range of innovative technologies. Thanks to their novel computing power, they can run simulations that help accelerate the development of materials and active ingredients, make climate models more precise, and solve complex logistical problems.  

To achieve such powerful computers, the smallest computational units, qubits, must be improved. This can only be achieved by addressing material and manufacturing issues and by taking fundamentally novel approaches. On the other hand, the system design also needs to be optimized to avoid interference and to scale up the number of qubits significantly. Therefore, in addition to technologically advanced superconducting qubits, semiconductor spin qubits based on entirely new physical effects are also being investigated. Finally, scientists are researching how quantum computers can be integrated into classical supercomputers in the future.

Helmholtz scientists cover the entire development chain, from researching fundamental quantum effects and developing new materials to developing components and systems for their application. In this way, Helmholtz is helping to develop an entirely new type of technology and bring it into application.
