Google sets 2029 deadline for Q Day preparedness
Change
Google set a 2029 deadline to prepare for Q Day.
Why it matters
Google assigned itself a 2029 target for readiness against Q Day. The timeline frames preparedness as implementing post‑quantum cryptography (PQC) to augment or replace elliptic‑curve and RSA algorithms. Q Day is defined by existing quantum computers achieving sufficient error‑corrected qubits to break public‑key cryptography. Historical estimates cited a drop from a billion physical qubits (2012) to 20 million physical qubits (2019) as benchmarks for breaking 2048‑bit RSA.
Implications
- · Requires replacement or augmentation of RSA and elliptic‑curve implementations with PQC algorithms for operators aligning with the 2029 timeline.
- · Compromise of confidentiality for decades‑old encrypted secrets held by militaries, banks, governments, and individuals once quantum systems reach the needed qubit/error‑correction thresholds.
- · Directs security and engineering teams to allocate resources and execution time to integrate PQC across infrastructure ahead of 2029.
Who is affected
- · Operators
