Euro-Q-Exa regular user operation

Euro-Q-Exa is a EuroHPC quantum computer located in Garching, Germany.

Euro-Q-Exa is based on superconducting qubits, arranged on a square lattice enabling complex quantum computations, facilitating quantum error correction approaches, featuring high-quality qubits and gate fidelities, and playing a pivotal role in executing quantum algorithms across a wider range of application domains.

The system is to be integrated into LRZ’s supercomputer via a unified hybrid software environment providing unique user experience.

While the system will initially offer 54 physical qubits, Euro-Q-Exa will be expanded by the end of 2026 with the installation of an upgrade offering 150 qubits.
