In many areas of science, computational tasks arise that cannot be solved by conventional computing methods as the computing power required increases exponentially with the size of the problem. An example of this kind of task would be the disassembly of prime numbers. Quantum computers, unlike conventional computers, are made for tackling such complex tasks. JARA scientists in the JARA Institute for Quantum Information undertake research in many different areas in order to implement the development of a quantum computer. Semi-conductor spin qubits are a major focus of their work, as they offer the most promising approach to quantum information processing.

The main challenge for the scientists in Aachen and Jülich, apart from maintaining the quantum states of the qubits over a long period of time so that algorithms can be carried out, lies with the increase in the number of entangled qubits. This is because an operational quantum computer needs millions of entangled qubits in order to complete the tasks required of it.
