Running the international quantum race

The race for quantum supremacy isn’t just between tech companies, but between nation-states as well.

Why it matters: The first country to produce effective, working quantum computers will have a key advantage in economics, defense and cybersecurity — and the U.S., China, and Europe are all competing.

What’s happening: Last month, the Commerce Department added a dozen Chinese companies to a trade blacklist in an effort to prevent emerging U.S. technologies from being used for quantum computing efforts that would boost Beijing’s military.
