Google announces quantum advantage, 13,000 times faster than supercomputers

Researchers at Google demonstrated the first verifiable quantum advantage by using their Willow Quantum processor and a technique called "quantum echoes" to map the structure of a molecule 13,000 times faster than the most powerful supercomputers. The "quantum echoes" technique involves targeting a single qubit with a precise signal, reversing the process, and measuring the resulting echo to gain detailed imaging. This experiment is verifiable, meaning others can reproduce the results on equivalent quantum systems. While current quantum computers are not powerful enough to break modern encryption (which uses key lengths up to 4,096 bits, while current quantum systems can only break about 22 bits), a sufficiently powerful quantum computer poses an existential threat to cryptocurrencies like Bitcoin, potentially rendering ECDSA obsolete by 2030. Experts and investors are urging the adoption of post-quantum cryptography standards, with the US SEC outlining a roadmap for such standards by 2035.
