Boeing [NYSE: BA] has revealed plans for the 2026 launch of its Q4S satellite, a mission aimed at demonstrating quantum entanglement swapping capabilities in space. This groundbreaking mission, fully funded by Boeing, seeks to advance efforts toward a secure, global quantum internet connecting quantum sensors and computers.

Quantum sensors offer unmatched precision compared to today’s best instruments, while quantum computers can process vast amounts of data, potentially revolutionizing industries. This experiment will explore how quantum networks can be established across great distances, maintaining high synchronization and efficiency.

Boeing is pioneering the future of information handling with quantum-enhanced applications that promise secure computing, fault-tolerant systems with reduced errors, and more. “Quantum entanglement swapping will extend quantum networks beyond basic point-to-point connections, and Q4S is our step toward proving this is possible in space,” said Jay Lowell, Chief Engineer of Boeing’s Disruptive Computing, Networks & Sensors division.

Entanglement swapping is based on quantum teleportation, a phenomenon where information can be transferred between particles without physically moving the particles themselves. Albert Einstein once referred to this as “spooky action at a distance,” highlighting the complexity of quantum mechanics.

Demonstrating this technology could enable scalable quantum networks capable of transmitting data over vast distances—currently limited by loss and decoherence. These capabilities could help researchers gather more detailed information about Earth and space environments, surpassing the limitations of today’s instruments.

“Boeing has a long history of pushing the boundaries of what’s possible,” said Todd Citron, the company’s Chief Technology Officer. “We are leading the charge in operationalizing quantum technologies and scaling them for global applications.”

The Q4S demonstration, set to last a year, will feature two entangled-photon pair sources aboard a space vehicle. Boeing’s technology partner, HRL Laboratories, has made significant progress in preparing the space-ready payload, advancing from benchtop exercises to final technical designs.

Boeing is a global leader in aerospace, developing and servicing commercial airplanes, defense systems, and space technology for clients in over 150 countries. Committed to innovation and sustainability, Boeing aims to lead the way in advancing technology and supporting economic growth.

HRL Laboratories, based in Malibu, California, specializes in cutting-edge physical and information science, delivering transformative technologies for the automotive, aerospace, and defense industries. As a private company owned by Boeing and General Motors [NYSE: GM], HRL is at the forefront of innovation, driving critical missions for its clients worldwide.
