Experts believe that one day, quantum computers could make today's encryption systems completely obsolete. But Google tells The Verge Its new “breakthrough” Wilo chip Nowhere is prepared for that.
“The Willow chip is not capable of breaking modern cryptography,” explains Charina Chou, director and COO of Google Quantum AI. The Verge,
So-called “cryptanalytically relevant quantum computers,” or CRQC, “could jeopardize civilian and military communications, undermine supervisory and control systems for critical infrastructure, and the security protocols for most Internet-based financial transactions. Can defeat,” the White House said. Warned in 2022Ordering that US agencies must transition to new systems to reduce that risk by 2035.
But according to Google, Willow is not CRQC. While the company claims it can solve a computing challenge in five minutes that would take the world's fastest supercomputer ten septillion years, Google has produced only 105 physical qubits worth of that computing power and suggested That he would need millions to crack the code.
“Estimates are that we are at least 10 years away from breaking RSA, and doing so would require about 4 million physical qubits,” Chow writes. She says that Willow doesn't change the timeline at all.
And although Chinese researchers have Frequently claimed Security experts have discovered new ways to break RSA encryption with very small quantum computers, consisting of only a few hundreds or thousands of qubits. Frequently Went confused,
The RAND Corporation, a think tank famous for advising on US national security in the past, Suggested in a 2023 editorial The moment an RSA-breaking quantum computer exists, it will cause a worldwide rush to defend against it:
“As soon as the existence of CRQC becomes public – or even considered plausible – and the threat becomes concrete, the most vulnerable organizations will immediately move to upgrade all of their communications systems to post-quantum cryptography. “
