A quantum computing deadline looms.
It threatens to kick off the biggest cybersecurity crisis ever
May 17, 2026
The clock is ticking on Q-Day, the looming yet unknown date when quantum computing will have the capacity to quickly and easily break the encryption keys that keep most internet communication safe.
Experts have known about the hypothetical risk of Q-Day since the 1990s. But Google recently warned that quantum computers may be able to hack some encrypted systems by 2029 — a timeline that drastically narrows the window to safeguard data that many cybersecurity specialists had previously predicted. The new estimate means that governments, companies and other entities may have far less time to prepare.
“It’s the day when people, perhaps adversaries, will have access to a quantum computer that can break cryptographic codes that are in use,” said Michele Mosca, cofounder and CEO of cybersecurity company evolutionQ.
Q-Day marks the moment a quantum computer gains enough resources and stability to crack conventional crytopgraphy. When that happens, every financial transaction, medical file, email, location history and crypto wallet protected by today’s commonly used algorithms could be unlocked by a machine capable of solving the complex math that currently keeps sensitive data secure.
At that game-changing turning point, “everything’s safe — safe, safe — and then suddenly it’s not safe. It’s a very drastic jump,” said Mosca, who is also a professor at the Institute for Quantum Computing at the University of Waterloo in Ontario.
Adversaries and bad actors may already be collecting encrypted data, with the intention of launching “harvest now, decrypt later” attacks. In this scenario, information is stolen, stored and then decrypted when a full-scale quantum computer is available, he added.

Re: A quantum computing deadline looms:
Or as with Y2K, will thousands of IT professionals spend billions of dollars fixing it first?
Have faith bobstar, remember both AI and QC are both emerging fields set to complement and resolve eachothers problems.
It's way above my own unqualified opinion, however I have forwarded this question of yours to someone dear to my heart, my son.
I should be interested to know myself what he thinks will happen.
I also sent this question to my dad, who knows a thing or two about this sort of thing too.

Ok Bobby, you have officially got me into strife with my son who genuinely knows exactly what he's talking about re- cyber security.
This is his response when I asked him what you asked here....
"CNN isn't real news. What has gotten into you? I thought you were more intelligent
We never had privacy and security , the NSA has had backdoors in everything since the 1940s , this is well known. "- by son
Thanks for this Bobstar, now my son thinks I've had a stroke.

You are welcome.
