At the Quside Showcase Day 2024, a panel of experts from Ericsson, Nestlé, and Equinix explored how quantum technologies are reshaping data center security and infrastructure. Moderated by Frank Malek, VP of Business Development at Quside, the discussion delved into the implications of post-quantum cryptography (PQC), quantum key distribution (QKD), and the challenges of future-proofing networks in an era of quantum threats.
Balancing PQC and QKD: The Ericsson perspective
Gemma Vall-llosera, Principal Quantum Engineer at Ericsson, emphasized the complementary roles of PQC and QKD in securing networks.
It’s not an either-or situation, PQC is more accessible and cost-effective for early adoption, but QKD addresses unique problems in securing the network core.
She highlighted the importance of internal readiness:
Even if a technology isn’t yet in production, the knowledge must exist within the company. If a client demands a QKD-secured network tomorrow, we need to be prepared.
This forward-thinking approach reflects the dual strategy of implementing PQC now while laying the groundwork for QKD’s broader adoption as it matures.
Data security at scale: Nestlé’s approach
For Jordi Mur, IT Innovation Lead at Nestlé, protecting data at rest and in transit across the company’s global operations is a top priority. With 340 factories and over 270,000 employees worldwide, the company faces unique challenges in safeguarding intellectual property and logistics data. Jordi shared:
We’ve tested both PQC and QKD, PQC offers a quicker path to adoption, but we’re agnostic. Our priority is balancing cybersecurity with operational continuity. We can’t afford to compromise customer experiences, like blocking access to the Nespresso app.
This pragmatic approach underscores the necessity of aligning quantum security measures with existing business priorities and ensuring seamless integration with legacy systems.
Enabling quantum readiness: Equinix’s role
Christophe Thioux, representing Equinix, discussed the company’s efforts to support quantum technology adoption. With over 270 data centers worldwide, Equinix is creating environments for clients to test and deploy emerging technologies like QKD.
The threat is real, even if quantum computers aren’t breaking RSA codes yet. We’re focused on enabling clients to evaluate the cost of not investing in quantum security versus the cost of being a victim.
Equinix has launched proof-of-concept projects across critical locations, helping clients navigate the transition to quantum-safe solutions while addressing challenges like compatibility with existing networks.
The essential role of randomness
Throughout the discussion, the critical importance of high-quality randomness emerged as a unifying theme. Gemma noted, “Both PQC and QKD rely on good random numbers for key generation and protocol execution”. Quantum random number generators (QRNGs), such as those offered by Quside, are vital for ensuring the security of both approaches.
Collaboration for a secure quantum future
The panel concluded with a shared acknowledgment of the need for industry collaboration. Companies like Ericsson, Nestlé, and Equinix are paving the way for secure and scalable quantum technology adoption in data centers by combining expertise in hardware, software, and operational needs.
As quantum threats evolve, organizations must act now to prepare for the future, leveraging the strengths of PQC and QKD while fostering innovation in randomness and infrastructure compatibility.
