Quantum computing could transform cryptography, sensing, and computation, and the states that master it first will gain a strategic edge. The race between the United States, Europe, and China to lead quantum technology is now a matter of national security as much as science. This hub follows that competition: the geopolitics of quantum computing, quantum encryption and the threat quantum advances pose to current cryptography, the government quantum initiatives funding the field, and the quantum security risks that come with them. Quantum encryption will decide whether today’s data stays safe, and the quantum race is pushing governments to act. Fellows and analysts weigh government quantum initiatives, quantum security, and how democracies can lead responsibly. Explore analysis and commentary on quantum computing, the quantum race, and its implications for security.
