Quantum Computing Meets AI: The Encryption Crisis Nobody Is Talking About
In February 2026, a research paper jointly authored by Google’s quantum computing division and Oratomic, a quantum hardware startup, sent shockwaves through the cybersecurity community. The paper demonstrated a new approach to quantum error correction that, if it scales as projected, could dramatically accelerate the timeline for a quantum computer capable of breaking RSA-2048 encryption: the standard that protects virtually all encrypted internet traffic, banking transactions, government communications, and digital signatures.
The previous consensus was that such a machine was 15-20 years away. The new research suggests it could be closer to 7-10 years. That’s close enough to be a planning horizon for banks, governments, and infrastructure operators. And almost nobody outside the security community is preparing for it.
Modern encryption relies on mathematical problems that are extremely hard for classical computers to solve. RSA encryption, for example, depends on the difficulty of factoring very large numbers into their prime components. A classical computer would take billions of years to factor the numbers used in RSA-2048. A sufficiently powerful quantum computer, using Shor’s algorithm, could do it in hours.
This isn’t theoretical hand-waving. The mathematics of Shor’s algorithm are well-established and uncontested. The only barrier is engineering: building a quantum computer with enough stable, error-corrected qubits to run the algorithm at the scale needed. What the Google-Oratomic paper changed was the estimation of how quickly that engineering barrier might be overcome.
The most insidious aspect of the quantum encryption threat is that it’s already active, even before quantum computers exist. Intelligence agencies and sophisticated attackers are engaged in what the security community calls “harvest now, decrypt later”: intercepting and storing encrypted communications today, with the intention of decrypting them once quantum computers become available.
For information that needs to remain confidential for years or decades: state secrets, medical records, financial data, trade secrets, personal communications: this means that today’s encryption may provide no long-term protection. Data encrypted and transmitted in 2026 could be readable in 2033 if quantum computing advances as the latest research suggests.
