But the geopolitical stakes of quantum technology are high: full-fledged quantum networks could provide unhackable channels of communication, and a powerful quantum computer could theoretically break much of the encryption currently used to secure e-mails and Internet transactions. Racing in the Quantum RealmIs China ahead of the U.S. in quantum information technology? China has more total patents across the full spectrum of quantum technology, but U.S. companies have a dramatic lead in quantum computing patents. And of course, China has a more sophisticated quantum network and now claims the top two quantum computers. Hawkish funding of quantum technology could further inflame relations, but it could also stimulate more cooperation and transparency between competing countries seeking to prove their quantum prowess.
