Google released that they have come up with a refinement to Shor's algorithm, which is a quantum computing algorithm for factoring which can be used for breaking encryption.

Quantum computing is getting closer — and so is the risk to today’s encryption (RSA, ECC).

At RELIANOID, we’re already preparing with crypto-agile architecture and early Post-Quantum Cryptography testing.

The future is coming. Security must evolve now.

Well, it’s good that someone is drawing a line in the Crypto sand.

Google accelerates its readiness timeline to prepare for “Q-day” with post-quantum cryptography (PQC) migration to 2029. Reminder: Q-day = the date when quantum computing becomes operational and is powerful enough to break the digital signatures that secure the Internet, crypto (blockchain + Ethereum), and just about every other Information system in use today.

The Bitcoin crypto network relies on ECDSA elliptic curve signatures. https://techaptitude.substack.com/p/ecdsa-cryptographys-role-in-securing With an exposed crypto signature public key, a quantum computer could derive the private key. And then, the crypto assets would be freely available to a hacker.

Android 17 will integrate ML-DSA, an algorithm standardized by the NIST to secure digital signatures. https://security.googleblog.com/2026/03/post-quantum-cryptography-in-android.html

In our latest Computing research we look at developments in quantum computing and cryptography, whether UK IT leaders believe the risk is real and what actions they are taking.

Two coordinated quantum cryptanalysis papers yesterday — same day, interlinked, complementary threat models:

Google (Babbush, Gidney, Zalcman + Ethereum Foundation + Stanford): ECDLP-256/secp256k1 compiled to surface code on planar superconducting arch. <500K physical qubits, ~9 min primed. Circuits withheld, verified via Groth16 SNARK over SP1 zkVM.

Oratomic (Cain, Xu, Bluvstein, Preskill, Endres, Huang): Same Google circuits compiled to high-rate lifted-product qLDPC codes (~30% rate) on reconfigurable neutral atoms. ~10K–26K physical qubits, ~10–264 days at 1ms cycle. Surgery gadgets are existence proofs, decoder-limited, LLM-assisted code search.

Together these bracket Google's own Scenario 1 (fast-clock on-spend) and Scenario 2 (slow-clock at-rest). The Oratomic arch solves Pinnacle's routing problem with atomic reconfigurability rather than non-planar wiring. Hardware gap: 6,100 demonstrated atoms → 10K needed (~2x) vs 1K demonstrated superconducting → 500K needed (~500x).

Neither paper moves Q-Day to next year. Both papers kill the "millions of qubits" comfort model.

Google bumps up Q Day deadline to 2029, far sooner than previously thought

Google is dramatically shortening its readiness deadline for the arrival of Q Day, the point at which existing quantum computers can break public-key cryptography algorithms that secure decades’ worth of secrets belonging to militaries, banks, governments, and nearly every individual on earth
