There are still some challenges to operate a quantum computer – and this is where micro- and nanoelectronics comes in as an enabler: If the components can be made ready for use in larger markets and outside laboratory environments by scaling, miniaturizing, reducing vulnerability to interference and lowering costs, the door to the world really is open for quantum computing.
Fraunhofer EMFT focuses on bridging the gap between quantum technologies and conventional micro- and nanoelectronics. The aim of the R&D work is to optimize the scalability, integrability and individual addressability of the qubits. In the long term, this should enable the development of up to 1000 qubit systems as the basis for quantum computers.
At Fraunhofer EMFT, micro- and nanotechnologies are available for the production of qubit chips and systems with a focus on scaling and manufacturing. With the help of production-compatible process technologies, for example for coating and structuring the qubit chips, superconducting quantum circuits can be manufactured in larger quantities. In perspective, this could enable next-generation quantum computers with up to 500 qubits.
State-of-the-art integration technologies such as heterogeneous 3D integration can be used to integrate and miniaturize the qubit chips at wafer level in order to realize the smallest possible, high-performance and energy-efficient quantum systems.
