The promise of quantum computing feels like something out of a sci-fi novel. We have heard about potentially huge breakthroughs in medicine and energy. However, its implementation in the real world still carries a hidden sting. Google recently issued a global call to action, warning that bad actors could use the quantum technology, originally designed to solve “impossible” problems, to dismantle the digital locks protecting our bank accounts, private messages, and national secrets.
Google warns: The quantum era could shatter today’s digital security
The most unsettling part of the quantum threat isn’t just about the future, but about what is happening right now. Malicious actors are currently engaging in “store now, decrypt later” attacks. They are vacuuming up vast amounts of encrypted data today, betting that a powerful quantum computer will eventually act as a “skeleton key” to unlock it in the coming years.
It’s noteworthy that these “cryptographically relevant” quantum computers don’t fully exist yet. However, the data being stolen today—like health records or trade secrets—could still be highly sensitive when they arrive.
For years, the arrival of a quantum computer capable of breaking standard encryption was seen as a problem for the next generation. Google’s leadership is now pushing back on that timeline. The move suggests that the window for preparation is narrowing faster than many expected.
In 2024, the National Institute of Standards and Technology (NIST) finalized the first set of post-quantum cryptography (PQC) standards. These are mathematical algorithms specifically designed to be “quantum resistant.” Google is already rolling them out across its infrastructure and products like Chrome. The Mountain View giant has been experimenting with these protections since 2016.
A roadmap for the quantum era
Protecting the digital economy from a quantum future is not a matter of just one company. Google has given governments and businesses a few important tips on how to stay ahead.
First, the company suggests updating the cloud infrastructure. Instead of spending billions trying to retrofit old, “hard-coded” legacy systems, organizations should move to cloud-based platforms that can update their security protocols automatically.
Google also suggests that current and future systems need to be designed so that encryption can be swapped out quickly as new threats emerge. Lastly, designing AI security from the core will be a fundamental requirement. As we become more dependent on artificial intelligence, its security must be built on a post-quantum foundation from the start.
Breakthroughs, not breakdowns
Google’s message to the tech community’s main message is clear: there’s no need to panic, but we need to get ready right away. For now, we just need to make sure that international standards are in line and that we move away from old systems that are easy to hack. This can help make sure that the quantum age is marked by scientific progress rather than security failures.
