Collaborative projects within the Competence Center Quantum Computing

The goal is to develop a diamond-based spintronic quantum register for a scalable quantum processor. For this purpose, a 10-qubit quantum register is being researched. This is the only register realized so far which will also have a quantum memory.

For companies, the ability to make optimal decisions quickly is increasingly becoming a decisive competitive advantage. Quantum computers can perspectively outperform conventional computers in optimization processes. The project is therefore developing such optimization algorithms and will test them in practical settings.

Using models and computer simulation methods of theoretical quantum physics, this research project deals with the question to what extent atomic defect complexes in crystals that can be addressed as qubits can be periodically arranged along linear structural defects and used as qubit registers for the construction of quantum computers. The focus of the investigations is on regular arrangements of a larger number of nitrogen vacancy centers (NV centers) in diamond crystals.

In the QuESt project the IBM quantum computer is used and tested for material simulations for electrochemical energy systems.

The atomistic modeling of batteries and fuel cells is the core topic of the project. Thermodynamic properties of solid electrode materials are calculated using a combination of density functional theory and a quantum physical approach for strongly correlated local electron states. Electrochemical reactions in liquid electrolytes are simulated using quantum chemical variation methods.

Stability and – if necessary – rapid and efficient error correction in the operation of system-relevant public infrastructure such as water and power supply or communications is of strategic relevance to the community. All these structures can be modeled as finite, usually coupled networks, but the rapidly growing complexity of conceivable fault scenarios, which increases with the size of the network, makes simulation-based problem intervention in real time difficult. By mapping typical network structures to quantum networks and implementing them on IBM quantum hardware, the potential of quantum mechanical interference effects for increasing the efficiency of such simulations will be explored.
