The Commerce Department on Friday barred US firms from exporting quantum computing technology Eight Chinese companies and laboratories for trying to prevent the country from decrypting sensitive US communications and developing new military technology.


“Global trade and commerce should support peace, prosperity and well-paid jobs, not national security risks.” Commerce Secretary Gina Raimondo said in a statement.

Although still technically immature, quantum computers may eventually crack traditional encryption. The US government is also leading an active program to develop post-quantum cryptography, but the communications disruptors that are today could be exposed if quantum computers become powerful enough.

quantum computer Take advantage of the physics of ultrasmall to perform a fundamentally different kind of computation than the traditional computer chips in today’s phones, laptops and supercomputers. But today they operate only on small scales, plagued with errors that derail calculations and are sophisticated enough to require ultracold conditions.

The department also pointed to quantum computing of military risks associated with “counter-stealth and counter-submarine applications.” It gave details of the Chinese organizations it added to List of Institutions include export controls federal register,

Another market where quantum computers also have potential is simulating molecular structures that could lead to new materials. Military technology has benefited immensely from materials science in the past, so quantum computing could lead to new breakthroughs.

To capitalize on these successes, several US companies are investing billions of dollars in developing quantum computers. Including Google, IBM, Microsoft, Honeywell, IonQ, Rigetti, D-Wave and Intel. Google chief executive Sundar Pichai said in November Chinese researchers linked with Google in a race to Develop quantum computing technology,
