SuperQuLAN

Superconducting quantum circuits are one of the most promising platforms for realizing large-scale quantum computing devices, where in the near future a coherent integration of 100-1000 quantum bits (qubits) is feasible. However, the required temperatures of only a few mK currently restrict quantum operations to qubits that are located within a single, heavily shielded dilution refrigerator. This imposes a serious constraint on the realization of even larger quantum processors or the implementation of local- and wide-area quantum networks based on this technology.

The project SuperQuLAN is set out to address this important open problem and to demonstrate a first operational prototype quantum local area network of separated superconducting quantum processors. This work will be carried out by a multi-national team of scientists and industry partners who will develop key network components and quantum communication protocols that will facilitate in the long term the realization of large quantum computing clusters or even city-wide quantum networks using superconducting circuits.

The project is funded by the Horizon 2020 research and innovation programme of the European Union.
