Quantum Networks Summit: What Customers Are Really Thinking About PQC, Performance, and the Road Ahead
The 2026 Quantum Networks Summit offered a rare window into how organisations are approaching the shift toward post‑quantum security. While the industry buzzes with theory and long‑term planning, customers at the event were focused on something far more immediate: how these technologies will actually behave in their networks.
Across conversations with operators, integrators, labs, and security leaders, a clear picture emerged of where customers are in their journey and what they need next.
Customers Are Hungry for Practical Answers, Not More Theory
Most attendees weren’t looking for abstract discussions about quantum threats. They wanted clarity on real‑world impact. The biggest question on their minds was simple: “What will PQC do to my network?”
Performance implications were top of mind. Customers know PQC is coming, but they don’t yet know how it will affect latency, throughput, or infrastructure design. They’re searching for data, testing experience, and lessons learned from early adopters.
The industry conversation is shifting from why PQC matters to how it behaves.
The Buyer Cycle Is Still Early, but Momentum Is Building
Customers are not yet in full procurement mode. Instead, they’re: building internal knowledge, scoping future test labs, exploring early architectures, comparing approaches to migration, and looking for trusted guidance.
This early stage is critical. Organizations are forming their mental shortlist of who understands the space, who has real experience, and who can help them navigate the transition.
The companies that educate the market now will be the ones customers return to when they’re ready to buy.
Common Challenges
Even though pain points weren’t expressed as complaints, several common themes surfaced at the summit.
- “Show me real testing experience.”
Customers want to see results, not roadmaps. They’re looking for partners who have already run PQC algorithms through real networks and can speak to the outcomes.
- “Help me understand the performance trade‑offs.”
While they know PQC will introduce overhead, they don’t know how much or where it will matter most.
- “What about HSMs?”
Hardware security modules (HSMs) were a hot topic. Many organizations are evaluating how PQC fits into their HSM strategy and are looking for validation tools.
- “Make it simple.”
In an industry heavy on jargon, attendees gravitated toward clear explanations that cut through complexity.
PQC’s Impact Across the Ecosystem
The audience was diverse, reflecting the broad impact quantum technologies will have across the ecosystem. Many were not exclusively focused on PQC or quantum security. This reinforces a key insight: quantum‑related decisions are no longer confined to cryptography teams, but are becoming cross-functional.
Emerging Signals for the Industry
A few trends stood out as indicators of where customer priorities are heading:
- PQC performance testing is becoming a must‑have, not a nice‑to‑have.
- HSM evolution is accelerating, and customers want clarity on how PQC fits.
- Test labs are being planned now, even if deployments are years away.
- Customers are forming their mental map of trusted experts in the PQC transition.
The Takeaway
The Quantum Networks Summit revealed a customer base that is engaged, curious, and preparing for a major shift in security architecture. They’re not ready to buy yet, but they are actively shaping their strategies and looking for partners who can help them understand the performance realities of PQC.
Based on conversations throughout the event, customers are looking for clear guidance on PQC performance impact, tools to validate algorithms and configurations, support for HSM‑related testing, education that demystifies quantum‑era security, and real‑world data to inform migration planning.
The companies that step up now, provide clarity, and share real‑world insights will be the ones customers trust when the transition accelerates.
