Microsoft is Accelerating Their Q-Day Readiness Timeline

Today, Microsoft published a blog post about the shifting timeline for Q-Day.

In essence,

“Advances in quantum research and development have shifted the risk horizon. We believe cryptographically relevant quantum computers could arrive sooner than previously expected—and the work required to prepare is significant so organizations need to start now.”

As I have stated before, acceleration is a feature of Quantum Computing. AI is driving acceleration, especially in error correction. Engineering and commercialization is driving acceleration in the availability of working quantum computers. Microsoft is taking note.

While I am putting Q-Day in 2028, Microsoft is shifting their timeline to be ready by 2029, which aligns with most major tech firms.

“In response to these shifts, we are accelerating the Microsoft Quantum Safe Program (QSP) timeline with the goal of transitioning critical products and services to PQC by 2029.”

Consider this another reminder to update your systems to support PQC.
