The Quantum Computing and Cybersecurity Revolution Is Here—And Your Clients Need You 

A new field report from the Quantum World Congress will reshape how you discuss cybersecurity.

By Sumera Riaz, Security Solutions Architect, Telarus

Remember the days when artificial intelligence seemed like a far-off science-fiction concept? Or when someone first mentioned “the cloud,” and you probably thought, “Where is this cloud everyone keeps talking about?” Fast forward, and now it’s just part of the everyday. It’s essential. 

Well, quantum computing and cybersecurity are following the same trajectory, and as technology advisors, this is our moment to get in front of it. 

My Takeaways from the Quantum World Congress 2025 

I just returned from the Quantum World Congress in D.C., and I cannot emphasize this enough:  

Quantum computing is no longer just a theoretical concept. It’s real, evolving rapidly, and poised to reshape how we think about technology, especially cybersecurity risks.  

Picture this: Telarus was in the same room with delegates from over 31 countries. Government experts from the NSA and Department of Defense (DOD). Representatives from the National Institute of Standards and Technology (NIST) and the Defense Information Systems Agency (DISA). The brightest quantum physicists and engineers, along with titans like Microsoft, IBM, and NVIDIA, and others, all sitting in one room to discuss the future of quantum computing and cybersecurity.  

The focus in that room wasn’t about when this technology would become viable; it was about how to make sure the world is ready for the profound changes that are coming as we speak.  

The post-quantum era is officially here, and it’s time to take action. 

How Quantum Computing is Different from Traditional Computing 

Let me break down quantum computing in the simplest way possible:  

Traditional computers think in binary: ones and zeros. They process one calculation at a time, like reading a book one page at a time.  

Quantum computers use qubits, which can be 0, 1, or both at the same time. This allows quantum computers to explore multiple possibilities at once thanks to super positioning and entanglement, solving complex problems faster than the most powerful supercomputers today. They don’t read the book page by page—they comprehend the entire book at once. It’s math vs law of physics.  

What does this mean practically? Quantum computers can solve in seconds what would take traditional computers years—or decades. 

How Quantum Computing Affects Cybersecurity (And Your Clients) 

Here’s where it gets real for your clients: Quantum computing will eventually break today’s encryption methods. Period.  

That data your clients think is safe behind today’s encryption? It might already be stolen, stored, and sitting in someone’s vault, waiting for the day quantum computing makes decryption effortless. It’s called harvest now, decrypt later. 

Today’s encryption that protects your clients’ sensitive information and secure communications (i.e., banking transactions, patient records, government files) relies on math problems that are practically impossible for classical computers to solve in a reasonable timeframe. A powerful quantum computer changes that equation entirely. 

Most of our current encryption standards (RSA and ECC, for example) depend on the difficulty of factoring large numbers or solving discrete logarithm problems. Traditional computers would need thousands of years to crack them. A fault-tolerant quantum computercould theoretically solve the same problem in hours or days. That’s the moment quantum computers and cybersecurity collide, and it’s why NIST didn’t wait for the hardware to catch up before publishing post-quantum cryptography standards. 

For your clients, this isn’t an abstract future risk. Any data with a long shelf life (health records, financial histories, national security files, intellectual property) is vulnerable right now under “harvest now, decrypt later.” Adversaries don’t need a working quantum computer today; they just need to store the encrypted data until one exists. 

This is why cybersecurity and quantum computing have become inseparable topics in boardrooms across government, finance, and healthcare. The conversation is no longer “if” quantum breaks encryption; it’s “when,” and whether your clients’ migration to quantum-resistant algorithms happens on their timeline or an adversary’s. 

The Timeline Is Shorter Than You Think 

This isn’t about panic—it’s about preparation. The shift is already underway.In 2024, NIST formalized the first post-quantum encryption standards, and by 2027, U.S. organizations are expected to have quantum-readiness roadmaps in place. International mandates are moving even quicker. The leaders who act now will define the next era of secure innovation.  

It’s also worth noting how in January 2025, NVIDIA CEO Jensen Huang predicted that quantum was 15-30 years away. By mid-2025, he had already revised that statement. At NVIDIA’s GTC Paris developer conference, Huang said that quantum is reaching an inflection point and could start solving real-world problems within a few years.  

As it turns out, large-scale fault-tolerant quantum computers are already here. In fact, IonQ and NVIDIA launched theirs earlier this year. Quantinuum’s “Helios” is coming soon. We’ve moved from theory → practical → marketable → hybrid consumption models, which are available today. The next stop is full commercialization, which is on track to occur in just two or three years. 

The First Movers: Who’s Leading the Charge? 

Here’s who’s driving this change initially, based on conversations with industry leaders at QWC.

• Government and aerospace sectors (FedRAMP, CMMC, and SLED clients) 
• Banking institutions (already starting their post-quantum journey) 
• Healthcare and manufacturing industries (the ripple effect is catching on)  

If you’re working with clients in these areas, it’s critical to begin these conversations now. And looking forward, quantum will eventually impact clients in all industries. 

How to Start the Quantum Security Conversation (Without Sounding Like a Sci-Fi Nerd) 

As a technology advisor, it’s important to avoid overwhelming or confusing clients about quantum computing and cybersecurity. So here’s the secret: Don’t start with quantum physics. Start with business impact.  

We recommend asking questions like:  

• “What does this mean for your data security?” 
• “How does this impact your compliance requirements?” 
• “What does your long-term resilience strategy look like?”  

Clients in critical infrastructure, especially those already dealing with FedRAMP, CMMC, or banking regulations, should also take the following actions:  

• Start a cryptography inventory 
• Launch post-quantum pilots 
• Build quantum considerations into long-term risk planning  

Pro tip: Frame it as foresight, not fear.  

When you bring quantum into the conversation, you’re not selling fear. You’re selling confidence. You’re saying: “I’m watching the horizon for you. Let me help you prepare.”  

Remember: Ten years ago, the cloud sounded impossible. A few years ago, AI felt like science fiction. Now, quantum is the next chapter—and it’s already being written. This isn’t about if it’s coming; it’s about how ready you’ll be when it does. The real risk isn’t quantum itself—it’s pretending it’s not. 

Common Objections and How to Answer Them 

When you bring up quantum security with a client, don’t be surprised if the first reaction is skepticism. Here’s how to handle the pushback you’re most likely to hear. 

“This sounds too far off to worry about.” 

Remind them this isn’t about predicting the exact year a quantum computer breaks encryption, it’s about the data being stolen today and decrypted later. If their data needs to stay confidential for more than a few years, the clock already started. 

“We just upgraded our security last year.”  

Traditional security upgrades and post-quantum readiness are different problems. Firewalls, endpoint protection, and access controls don’t address the underlying math that quantum computers threaten. A recent security refresh is a good foundation, but it isn’t a substitute for a cryptography inventory. 

“Isn’t this just a vendor pushing new products?”  

This is a fair instinct, but think of quantum-readiness as a planning exercise rather than a product sale. A cryptography inventory and a migration roadmap cost far less than a breach. 

Handled well, these conversations position you as the advisor who is thinking ahead about quantum computers and cybersecurity.. This type of foresight turns into long-term trust. 

The Bottom Line 

The key takeaway is that the quantum era isn’t coming. It’s already here. And your clients need technology advisors who are ready to lead them through it.  

Fortunately, you don’t need to be a quantum physicist to help build quantum-ready environments. You need to be a trusted guide who can translate complex tech into practical action.  

We recommend starting small:  

• Identify clients in high-risk verticals (government, banking, healthcare) 
• Ask if quantum security is on their radar yet 
• Offer to explore what post-quantum readiness looks like for their organization
