Quantum Computers Could Crack Today's Encryption 100x Faster

Two new research papers argue that breaking 256-bit elliptic-curve cryptography will take far less quantum resources and time than was previously believed.

On the latest episode of the AI Inside podcast, Jeff Jarvis and Jason Howell discussed what these findings mean for the timeline of Q-Day, the day quantum computers can break today's mainstream public-key encryption. One team showed how ECC-256 could be cracked in about 10 days, roughly a 100x reduction compared to prior estimates. Separately, Google researchers say Bitcoin's secp256k1-based ECC could be cracked in under 10 minutes on around 500,000 physical qubits. Current platforms have demonstrated arrays of more than 6,000 qubits, and the hosts stressed that work needs to be done now to move real-world systems to post-quantum algorithms before it's too late.
