Story summary

Galicia Supercomputing Center and Universidad de Santiago de Compostela developed CUNQA, an open-source emulator for distributed quantum computing in HPC infrastructures.
CUNQA simulates three models—no communication, classical, and quantum communication—letting researchers test architectures before hardware exists.
The tool supports integrating quantum systems into HPC infrastructures, enabling progress in quantum computation.
China unveiled a photonic quantum chip reportedly accelerating calculations by over a thousandfold, though stability and general-purpose use remain concerns.
