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 op...

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 es...

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 confid...

The protocol in detail The history of the non-stop contest between cryptographer and decipherers traces back to the cave ages and has seen many victories for both sides. Terra Quantum bases its solution on the Vernon’s cipher, the so-called ‘one-time pad’, proven by Claude Shannon to be unbreakable. Terra Quantum introduces the superfast quantum key distribution, establishing a practical realization of this procedure in the context of the modern superfast information communications service. The innovative Terra Quantum protocol, the superfast Boltzmann-Planck-protected secure informati...

Quantum computers could in several years be used to break some widespread encryption algorithms, the company said
