Google’s quantum computing team has reduced the estimated quantum power needed to break RSA-2048 encryption from 20 million to under 1 million noisy qubits—a major leap that could impact digital security across industries.

The breakthrough suggests that a 2048-bit RSA key, still widely used in banking systems, legacy infrastructure, and even some $BTC wallet implementations, could theoretically be cracked in under a week.

While Bitcoin predominantly uses elliptic curve cryptography (ECC) rather than RSA, the study has reignited discussions about the quantum vulnerability of crypto networks and the timeline for adopting post-quantum cryptography standards.
