Quantum Computers Need Vastly Fewer Resources Than Thought to Break Vital Encryption
Recent research shows that building a quantum computer capable of breaking 256-bit elliptic-curve cryptography (ECC) requires far fewer qubits and resources than previously estimated, potentially compromising critical encryption much sooner than expected. One study demonstrated that neutral-atom qubits could break ECC-256 in 10 days with 100 times less overhead, while Google researchers showed quantum circuits breaking ECC on Bitcoin within nine minutes using 20 times fewer resources, highlighting accelerating progress in cryptographically relevant quantum computing.
