Quantum computers can break major encryption method, researchers claim

It’s long been known that one day quantum computers will be able to crack the RSA encryption method used to keep data safe, but researchers now believe it’s already possible. However, other researchers say the results need further scrutiny.

Researchers claim that quantum computers can now crack the encryption used to protect emails, bank accounts, and other sensitive data. While this has long been a theoretical possibility, existing quantum computers were not yet thought to be powerful enough to threaten cryptography.

But security experts have questioned the new claims, saying that while code-breaking techniques appear to work, there is no reason to expect them to be able to crack encrypted data on a practical timescale, and current quantum hardware Ware also said…
