Researchers, including teams from the University of Vienna, are advancing the practical applications of quantum computing in both terrestrial and orbital environments.

In Austria, a collaborative research group is developing a novel electron microscope powered by a quantum computer. This system aims to use quantum entanglement to link incoming microscope electrons to a quantum processor, allowing for high-clarity imaging of sensitive biological specimens while reducing the total electron load that could cause damage.

Separately, physicists have successfully operated a quantum computer in space for the first time. Led by Philip Walther, the University of Vienna team utilized a photonic quantum processor that encodes information using light-based qubits on a glass chip. Launched via a SpaceX Falcon 9 rocket, the device reached a low Earth orbit of approximately 510 kilometers on June 23, 2025.

Despite facing critical technical challenges—including mechanical stress during launch, solar interference, radiation, and thermal fluctuations—the team demonstrated essential quantum effects. This achievement suggests that quantum computing could eventually be used to process massive amounts of raw data directly on satellites. While some satellites currently use AI chips for onboard processing, quantum computing offers the potential to resolve significant bandwidth bottlenecks by processing atmospheric, climatic, and photographic data in orbit and sending only the processed results back to ground stations.
