Quantum: The Day Encryption Stops Working

Last week, Ethereum announced it is forming a post-quantum working group because they can read the room: cryptography isn’t a “future upgrade,” it’s a ticking dependency and a grown-up admission that digital trust has a shelf life.

In Now What? I called this the Big Crunch: the moment quantum collapses the economics of breaking today’s public-key cryptography. Unlike Y2K, this isn’t a bug you patch. It’s a global migration you either start early or you finish in panic.

And timelines are already wobbling, Google research from 2025 suggested breaking RSA could need 20x fewer qubits than previously thought of.

Unfortunately, most leaders treat quantum like a storm on the horizon: “interesting, but not today.” That’s a mistake. Attackers can already copy encrypted traffic and files now, store it, and unlock it later when quantum tools get good enough.

That’s not theory. It’s a rational investment strategy from an adversary's perspective. And if a major system ever gets quietly cracked, you won’t hear about it when it happens. You’ll hear about it after someone has made money from it. After all, the incentives reward silence; think Enigma, but automated, monetized and at scale.

The smart path is boring, but effective: start upgrading before the break, and form working groups like Ethereum to start today. It also means running hybrid encryption, today’s algorithms paired with post-quantum ones, across the places where trust lives: web connections (TLS), logins and identity, enterprise software, key management and HSMs, cloud services, and blockchain signatures.

Do it early and you turn a cliff-edge event into a controlled rollout. Wait too long and it’s not just your future data at risk, old encrypted backups, archived emails, contracts, customer records, IP can become readable years later. In other words: you don’t just lose security going forward. You lose your history.

I’ve always insisted: resilience is built before the wave hits. Quantum is that wave. What are you migrating first, your systems, or your excuses?

'Synthetic Minds' continues to reflect the synthetic forces reshaping our world. Quick, curated insights to feed your quest for a better understanding of our evolving synthetic future, powered by Futurwise:

1. Elon Musk's SpaceX is taking a bold step into the future with its plan to launch a data center constellation of up to 1 million satellites in low-Earth orbit. With SpaceX just announcing it will acquire xAI, this creates a vertically integrated stack where AI, satellites, communications, and compute all sit under one roof. (Gizmodo)

2. The era of truth decay, where AI-generated content erodes societal trust, appears to be here. The crisis demands a new masterplan to address deepfakes and AI-generated content, moving beyond mere transparency and verification tools. (MIT)

3. Imagine a robotic hand that can crawl away from its arm, outperforming human dexterity in controlled manipulation tasks. The EPFL robotic hand can do just that. It is a highly dexterous, modular device capable of outperforming human dexterity in controlled manipulation tasks. (NewAtlas)

4. The integration of synthetic biology and electronics has led to the development of energy-efficient bioinspired electronic devices. A game-changer for sustainable tech solutions. (Bioengineer)

5. The rapid adoption of AI is transforming the job market, with tech giants cutting thousands of jobs and sparking conversations about universal basic income. (The Currency Analytics)

Frequently asked questions

Why is quantum computing a threat to encryption?

Quantum computing threatens to collapse the economics of breaking today's public-key cryptography, meaning encrypted systems that once took impractical amounts of effort to crack could become vulnerable. This isn't a simple bug to patch like Y2K, but a global migration that organizations either start early in a controlled way or must scramble to finish under panic once quantum tools become powerful enough.》

What is 'harvest now, decrypt later'?

It describes how attackers can already copy encrypted traffic and files today, store them, and unlock them later once quantum tools become capable enough to break current encryption. This is a rational investment strategy from an adversary's perspective, meaning data being transmitted or stored now could be exposed years down the line, even though it appears secure under today's standards.

Link to this question

What happens if organizations wait too long to upgrade encryption?

Waiting too long puts more than future data at risk. Old encrypted backups, archived emails, contracts, customer records, and intellectual property can become readable years later once quantum tools mature. In other words, delaying migration means an organization doesn't just lose security going forward, it loses its history, since historical records could retroactively become exposed.

What should organizations do to prepare for quantum threats?

Organizations should start upgrading before quantum breaks current encryption, forming dedicated working groups the way Ethereum has. This includes running hybrid encryption, pairing today's algorithms with post-quantum ones, across every place trust lives: web connections, logins and identity, enterprise software, key management and hardware security modules, cloud services, and blockchain signatures. Acting early turns a cliff-edge event into a controlled rollout.
