An international team of scientists led by Philip Walther from the University of Vienna has successfully launched the first photonic quantum computer designed to withstand the extreme conditions of space. For the first time, a quantum processor has been integrated into a satellite now orbiting the Earth at around 550 kilometers.The launch took place on Monday, June 23, from Vandenberg, California. Communication with the satellite is expected to be established within two weeks, marking the start of groundbreaking experiments in space-based quantum technology.”This mission pushes the limits of current photonic technologies and opens the door for innovations that could transform future space missions,” said Philip Walther, the project lead.The device, built to fit within a shoebox, is energy-efficient and capable of running autonomously despite harsh thermal and mechanical shocks. Researchers adapted laboratory-grade photonic components to be compact, robust, and remotely controllable, in compliance with strict space safety standards.The Austrian-led team collaborated with the German Aerospace Center, the National Research Council in Milan, the Austrian Academy of Sciences, and the Viennese start-up Qubo Technology. Together, they developed, tested, and integrated the quantum computer and its components for space readiness.”This collaboration places Europe at the forefront of space-ready quantum computing and could pave the way for energy-efficient satellites of the future,” Walther added.
