Google Accelerates Post-Quantum Cryptography Migration Deadline to 2029 Amid Faster Quantum Hardware Progress

Google LLC has set an accelerated migration deadline of 2029 for post-quantum cryptography, significantly earlier than the National Security Agency's 2031 target and NIST's 2035 guideline. This acceleration is attributed to faster-than-expected advancements in quantum hardware and error correction, which have reduced the estimated number of qubits required to threaten current encryption.
