Come up with new form of post-quantum encryption

A Swiss technology company says it has made a breakthrough by using quantum computers to uncover vulnerabilities in commonly used encryption.

Terra Quantum AG said its discovery "upends the current understanding of what constitutes unbreakable" encryption.

Terra Quantum AG has a team of about 80 quantum physicists, cryptographers and mathematicians, who are based in Switzerland, Russia, Finland and the US.

Markus Pflitsch, chief executive officer and founder of Terra Quantum, warned that what was being seen as post-quantum secure fails to live up to its billing.

The company said that its research found vulnerabilities that affect symmetric encryption ciphers, including the Advanced Encryption Standard, or AES, which is widely used to secure data transmitted over the internet and to encrypt files.

Using a method known as quantum annealing, the company said its research found that even the strongest versions of AES encryption may be decipherable by quantum computers that could be available in a few years from now.
