A report that no one wanted to see is making the rounds in the Pentagon’s confidential briefing rooms. According to Chinese researchers, they broke RSA encryption in about 11 minutes using a quantum computer. Smaller keys—50-bit and 128-bit—using a D-Wave quantum annealing technology rather than the theoretical method everyone anticipated, rather than the full 2048-bit standard that safeguards everything from financial transactions to military communications. The trajectory is more important than the distinction. With quantum technology, what took decades for classical computers now just takes minutes. Furthermore, the gap is decreasing more quickly than the cryptography community had predicted.
The headlines scream “encryption broken,” which is neither entirely true nor entirely incorrect. Large prime numbers are difficult for classical computers to factor, making it practically impossible for keys larger than a particular size. This is the basis of RSA encryption. That math is altered by quantum computers, at least in principle. Developed in the 1990s, Shor’s algorithm provides a way to factor big numbers tenfold quicker than traditional methods. However, Shor’s technique necessitates fault-tolerant quantum computers with thousands of stable qubits, which are currently unattainable. The Chinese researchers took a different approach. They cracked smaller RSA keys using quantum annealing, a less potent but commercially available method. The accomplishment is genuine. What’s next is the source of the panic.

Technically speaking, D-Wave’s quantum annealing systems differ from the gate-based quantum computers being developed by IBM, Google, and other companies. Annealing is not optimized for general computation, but rather for particular optimization issues. It has a limited scope yet is faster for some jobs. The fact that researchers modified this technology to crack RSA keys—even tiny ones—indicates that quantum cryptanalysis is developing in more ways than just the widely followed Shor’s algorithm approach. Diversification is important. The timeframe for creating defenses shortens if encryption is threatened by numerous quantum techniques.
The atmosphere is apparently tense in McLean, Virginia, where the National Security Agency’s headquarters overlooks wooded hills and parking lots filled of experts who spend their days contemplating precisely this possibility. The Chinese study report was delivered to the Pentagon many months ago. Although officials haven’t made any public remarks, their silence says a lot. Classified communications, banking systems, vital infrastructure control networks, and pretty much everything else that matters in a digital economy are all protected by RSA encryption. Entire security architectures fall apart if quantum computers are able to break it—not theoretically, but practically. Banks are unable to operate. Command and control in the military are jeopardized. The current state of the internet becomes essentially unstable.
What was altered was the timeline. Five years ago, experts projected that it would take until the 2040s or possibly the 2050s for quantum computers to be able to crack 2048-bit RSA. That period has been significantly shortened by recent developments, such as this Chinese study. It may occur by the early 2030s, according to some analysts. Less than ten years remain till then. Before then, governments and businesses must switch to quantum-resistant encryption, which entails updating billions of devices, adopting new cryptographic standards, and rewriting software that relied on RSA’s perpetual security. The scope of the issue is astounding.
The strategic dimension is another. What else is China investigating behind closed doors if they have proven they can perform quantum cryptanalysis on smaller keys? Seldom is the most innovative research published in scholarly journals. Applications for the military and intelligence services remain secret. More sophisticated quantum systems might already be investigating flaws, attacking bigger keys, and developing attack plans for when the hardware catches up. Without a doubt, the United States, Russia, and other powerful nations are following suit. Encryption is one of the main fronts in the fight toward quantum computing.
At least in principle, the cybersecurity community has been getting ready for this. A competition to create post-quantum cryptographic algorithms—new encryption techniques intended to fend off quantum attacks—has been held by the National Institute of Standards and Technology. Standardization is in progress after a number of potential algorithms were chosen. However, it takes years to implement these standards throughout the world’s infrastructure. Transaction systems must be updated by financial organizations. Data must be re-encrypted by cloud providers. Quantum-resistant chips must be produced by hardware manufacturers. None of this happens quickly, and every delay increases the window of vulnerability.
The asymmetry is what’s disturbing. It is illegal to crack encryption. Defense is the development of quantum-resistant technologies. Offense only needs to succeed once to compromise a system. Defense must always be successful. When quantum computers get strong enough, attackers will be able to gather encrypted data now and decipher it later. This tactic, known as “store now, decrypt later,” implies that private data that is encrypted now may become public in five or 10 years. Anything sent or stored using existing encryption standards could be vulnerable in the future, including private communications, corporate intellectual property, and government secrets.
It seems like the world is sleepwalking toward a cryptographic cliff as we see this develop. The Chinese research made headlines for a day or two, then faded from public attention. But inside government agencies, defense contractors, and cybersecurity firms, the urgency is palpable. Plans for post-quantum migration are being accelerated by working groups. Vendors are releasing quantum-resistant encryption products. Standards organizations are working quickly to complete specifications. Yet the broader public remains largely unaware that the encryption protecting their bank accounts, medical records, and private messages could become obsolete within a decade.
The Pentagon’s silence on the Chinese report suggests careful calculation. If the threat is acknowledged too openly, it might cause panic or expose secret evaluations of U.S. quantum capabilities. You run the risk of becoming complacent if you downplay it. The middle path is quiet preparation—funding quantum research, mandating encryption upgrades for critical systems, and hoping the transition happens before adversaries achieve full cryptanalytic capability. Whether that hope is realistic depends on technological progress no one can predict with certainty. The development of quantum computing happens in erratic spurts. It might take another fifteen years or a breakthrough could occur tomorrow.
It’s hard not to notice the parallels to nuclear weapons development. Before both technologies abruptly became practical, they were theoretical for decades. Both have strategic implications that extend far beyond their immediate applications. Both create incentive structures where nations race to develop capabilities while simultaneously fearing their deployment. Quantum computers won’t destroy cities, but they could cripple economies and compromise national security in ways that are equally destabilizing. The difference is that encryption is everywhere, embedded in systems most people never think about until they fail.
The 11-minute timeline in the headline is specific, concrete, and terrifying in its implications. Classical computers would take years to crack the same key. Quantum systems did it in less time than it takes to brew coffee. Scale that capability up to 2048-bit keys and the entire digital security infrastructure collapses. Whether that happens in 2030, 2035, or 2040 is almost irrelevant. It’s coming. The Pentagon knows it. The cryptography community knows it. And now, slowly, the rest of the world is starting to figure it out too. The question isn’t whether quantum computers will break RSA encryption. It’s whether we’ll have viable alternatives deployed before they do. The clock is running. And 11 minutes doesn’t leave much margin for error.
