World’s first quantum satellite computer launched in historic SpaceX rideshare

The world’s first quantum satellite computer was launched into orbit on June 23, 2025, aboard a SpaceX Falcon 9 rocket as part of the Transporter 14 rideshare mission. Developed by an international team led by Philip Walther at the University of Vienna, this compact photonic quantum processor is designed to operate approximately 550 kilometers above Earth. The satellite aims to test the durability and performance of quantum hardware in the harsh conditions of space, including extreme temperature fluctuations, radiation, and vibrations. The device was assembled rapidly in a clean room at the German Aerospace Center, marking a significant engineering achievement. This quantum computer’s primary advantage lies in its ability to perform edge computing in orbit, processing data onboard rather than transmitting raw data back to Earth. This capability can enhance applications such as forest fire detection by reducing energy consumption and improving response times. Utilizing light-based optical systems, the processor efficiently handles complex computational tasks like Fourier transforms and convolutions. The system is adaptable for future missions and holds
