Switzerland beats UK to claim quantum computing breakthrough
Terra Quantum s discovery could lead to global secure networks for banks and governments
3 May 2021 • 10:00am
A Swiss quantum computing start-up has claimed a major breakthrough in encryption technology, beating British technologists to develop a system that can send theoretically unhackable messages around the world.
Terra Quantum, a Swiss business developing ways to keep sensitive information safe from the ability of quantum computers to break traditional encryption, has found a new method of securely sending data on fibre optic cables for up to 40,000km (24,850 miles).
The company’s new secure transmission method works using quantum key distribution, which is a way of sending data using quantum mechanics that many physicists say makes it impossible for hackers to intercept the data without alerting either side.
Inside the race to keep secrets safe from the quantum computing revolution
Start-ups are taking part in a global competition to upgrade encryption to fend off the quantum computing threat
28 February 2021 • 12:00pm
The algorithms that have kept state secrets safe and confidential messages private since the 1970s are about to be broken.
Security experts disagree on how long it will take - some say within five years, others a decade. But they’re all convinced that it’s just a matter of years until it happens.
Encryption will be broken not by a group of skilled hackers or via industrial espionage, but through breakthroughs in quantum computing, allowing governments to perform calculations that can untangle the complex mathematics that have kept our privacy for decades.
Security experts have long worried that advances in quantum computing could eventually make it easier to break encryption that protects the privacy of people’s data. That’s because these sophisticated machines can perform calculations at speeds impossible for conventional computers, potentially enabling them to crack codes previously thought indecipherable. Now, a Swiss technology company says it has made a breakthrough by using quantum computers to uncover vulnerabilities in commonly used encryption. The company believes it’s found a security weakness that could jeopardize the confidentiality of the world’s internet data, banking transactions and emails. Terra Quantum AG said its discovery “upends the current understanding of what constitutes unbreakable” encryption and could have major implications for the world’s leading technology companies, such as Alphabet Inc.’s Google, Microsoft Corp., and International Business Machines Corp.
