A global race is underway to harness the power of atoms for navigation, computing, and encryption. Governments are investing heavily, and scientists are making rapid advances in quantum technologies. However, concerns over protectionism and the need for cooperation are creating challenges.

Quantum sensors are being developed to create super-accurate navigation systems that can operate even when satellite GPS networks are jammed. These systems offer significant improvements over current technology, with minimal directional errors and robust portability. Start-up company Q-CTRL recently signed a deal with Australias Department of Defense to develop and field-test their quantum sensor technology.

The United States, in particular, is considering tougher export controls for quantum technologies to maintain an edge over China. However, allies argue that more limitations could stifle momentum and hinder the American model of tech development, which relies on openness and international collaboration.

The challenge for the United States and its allies is how to balance protectionism and cooperation in a field where talent is scarce and less concentrated in the U.S. Maintaining interdependence will be crucial for progress in quantum technologies.

China has taken a centralized approach to quantum technology development and has produced results that rival or exceed the American approach. Recent advances include the construction of a large national laboratory for quantum science and the establishment of a space-to-ground quantum communication network. Chinas investments in quantum technology were triggered, in part, by revelations of U.S. and British intelligence agencies cracking encrypted internet traffic.

While China appears to be lagging in quantum computers, progress in quantum sensing for navigation, mapping, and detection is narrowing the gap. However, some of Chinas quantum claims have been questioned by experts outside of the country.

Companies like Q-CTRL, with offices in Sydney, Los Angeles, Berlin, and Oxford, are among the leaders in global quantum technology. They see technology-sharing partnerships, like the AUKUS security agreement, as opportunities to capitalize on their capabilities.

The global race to harness the power of atoms for navigation, computing, and encryption is intensifying. Achieving a balance between protectionism and cooperation will be crucial to ensure progress in this transformative field.
