Google Updates Quantum Threat to ECC-256 as Only 19% of CISOs Act on PQC

Summary
Google Research updated its estimate of the qubits and gates needed to break 256-bit elliptic curve cryptography, sharpening the case for faster post-quantum cryptography adoption.
ECC underpins internet, mobile and blockchain security, and experts say the risk is no longer theoretical because attackers can harvest encrypted data now for later decryption.
IBM’s late-2025 survey of 750 CISOs found a readiness gap: 73% recognized quantum preparedness as important, but only 19% had taken tangible PQC steps.
That lag is compounded by unclear ownership—63% of security leaders called PQC a vendor problem—while migration will require crypto-agility across keys, certificates and authentication systems.
Beyond the threat, executives and researchers say quantum computing is spawning demand for cybersecurity, engineering and software talent as the field moves toward commercialization.
With hackers hoarding encrypted data today, is your organization already a victim of a quantum attack that hasn't happened yet?
Since larger post-quantum certificates threaten to slow networks, how will companies balance impenetrable security with demands for instant connectivity?
As quantum computers edge closer to breaking blockchain security, what happens to billions in dormant crypto assets when encryption fails?
