VLQ

The VLQ quantum computer, a joint collaboration between EuroHPC JU and the LUMI-Q Consortium, is hosted at IT4innovations and represents a significant advancement in European quantum computing infrastructure.

Equipped with 24 superconducting transmon qubits arranged in a unique star-shaped topology, the VLQ architecture significantly reduces the need for swap operations—a common bottleneck in many quantum circuits—thereby optimizing the utilization of coherence time and enhancing computational efficiency. This innovative design allows for more reliable, coherent quantum calculations and experiments.

The system’s user-friendly accessibility is highlighted by its compatibility with widely used quantum programming frameworks such as Qiskit and CIRQ, enabling seamless integration into existing quantum research workflows. Additionally, researchers can leverage the power of the integrated Karolina supercomputer to offload more complex hybrid quantum-classical tasks.
