What if a message could be protected by the laws of physics—not just by encryption?In this video, we explore the real promise of quantum networking and the science behind the no-cloning theorem, quantum entanglement, trusted nodes, quantum repeaters, and the race to build a true end-to-end quantum internet.We also look at what is working today, including China’s large-scale quantum communication network, and what is still holding the industry back. The biggest challenges are not the theory, they are the engineering bottlenecks involving distance, quantum memory, hardware interoperability, switching, and network emulation.You will learn:• Why quantum data cannot be copied• How eavesdropping leaves a detectable fingerprint• Why trusted relay stations remain a security risk• How entanglement swapping and quantum repeaters work• Why quantum memory is one of the biggest technical obstacles• How digital twins and virtual emulators are helping engineers test quantum networks• The three-stage roadmap toward a global quantum internet• Why “harvest now, decrypt later” is accelerating investment in quantum securityQuantum networking is not simply a faster version of today’s internet. It represents an entirely new approach to communication, security, and distributed computing.For the last century, we built the internet around the ability to perfectly copy information. The engineering race of the next century may be defined by the ability not to.#QuantumNetworking #QuantumInternet #QuantumComputing #QuantumSecurity #Cybersecurity #QuantumCommunication #PostQuantumCryptography #Technology #FutureOfNetworking #ACGResearch

For the last two years, the AI infrastructure conversation has been dominated by GPUs. But as AI clusters scale to tens of thousands — and eventually hundreds of thousands — of GPUs, the real bottleneck is shifting.The next AI infrastructure challenge is not just compute.It is interconnect.In this episode of The Deep Edge Podcast, Ray Mota breaks down why optical networking is becoming the foundation of AI data centers. From 800G and 1.6T optics to Linear Pluggable Optics, Co-Packaged Optics, Optical Circuit Switching, and silicon photonics, the future of AI depends on how fast, efficiently, and reliably GPUs can communicate.A GPU waiting on data is stranded capital. And optical is what keeps the AI factory moving.Topics covered:Why copper is reaching its physical limitsWhy AI clusters need massive east-west bandwidthThe role of 800G and 1.6T opticsLinear Pluggable Optics and Co-Packaged OpticsOptical Circuit Switching and flatter AI networksWhy optical efficiency directly impacts AI economicsWhy light, not just compute, will define the next AI buildoutKey takeaway: Compute gets the headlines, but optical holds the AI factory together.

Everyone is talking about the GPU shortage. GPUs are expensive, scarce, power-hungry, and central to AI infrastructure. But the real issue is much deeper.In this episode of The Deep Edge Podcast, Ray Mota breaks down why AI infrastructure is not fundamentally a GPU problem — it is a network economics problem. As AI workloads scale, the hidden bottleneck is not just compute capacity, but the ability of the network to move data efficiently, keep GPUs utilized, reduce latency, control power consumption, and avoid massive infrastructure wasteRay explains why enterprises, service providers, and hyperscalers must rethink AI infrastructure through the lens of network design, utilization economics, east-west traffic, data movement, automation, and total cost of ownership.The key message: buying more GPUs will not solve the problem if the network cannot support the economics of AI at scale.

Starbucks has recently pulled the plug on their AI inventory tool, after just 9 months in 11,000+ shops.The bigger lesson for me is simple:AI cannot solve an operations problem it does not understand.The technology was designed to utilize computer vision and spatial intelligence to count inventories faster and more precisely. On paper it sounds powerful. But in the real world, it apparently confused products, failed to find items on shelves, and made stockout concerns worse, not better.This is not a Starbucks problem. It’s a larger lesson for enterprise AI.Many firms are trying to expand AI without even understanding the operational challenge, the workflow, the human behavior and execution environment. AI doesn’t instantly produce process discipline. It magnifies the quality, or the fragility, of the underlying operational model.Some major take-aways:Speed is not preparation. Scaling AI to thousands of locations fast might seem daring, but success in the pilot does not always translate to success in production.AI requires operational context. If the fundamental cause is supply chain consistency, replenishment timeliness, store level execution, or process variation, then counting faster is not the issue.Frontline feedback is important. The failure sites are commonly seen by employees closest to the work. That signal is ignored, delaying adjustment and increasing risk.The design of the integration is as crucial as the AI model. Enterprise AI success isn’t about claims of accuracy. It’s about workflow fit, process reform, data quality, governance, training and adoption.Enterprise AI’s biggest danger isn’t the adoption. Scaling prematurely without properly diagnosing the business and operational problem.AI is powerful, but we need to relate it to the realities of how work really gets done.”What’s your take: are corporations rushing too fast to implement AI before they properly grasp the operational difficulties they are seeking to solve?#AI #EnterpriseAI #DigitalTransformation #RetailTech #SupplyChain #Operations #TechLeadership 

In this episode of The Deep Edge Podcast, Ray Mota breaks down one of the most important questions facing network architects, CTOs, and business leaders building next-generation AI data centers: how to make the right infrastructure investment decisions with real confidence.Ray explains why the economics of AI data centers are fundamentally different from traditional enterprise networks. In the AI era, the biggest investment is often the GPU cluster, and the network’s role is no longer just to provide connectivity. Its job is to keep high-value GPU resources fully utilized. When the network underperforms, the result is not just lower performance. It can mean lost revenue, delayed service delivery, and direct destruction of capital efficiency.The episode explores why financial modeling tools such as economic digital twins are becoming essential for planning AI infrastructure. Ray also outlines the critical questions every organization should quantify before committing capital, including the cost of GPU idle time, the CapEx-to-OpEx tradeoffs of different architectures, and the break-even point for transport decisions under varying growth scenarios. This is a practical and executive-level discussion on why AI infrastructure decisions must now be guided by modeled economics, not vendor slides.

I use AI to create this podcast, let me know what you think?The ACG Research study highlights how application-driven traffic is reshaping the economics of fixed and mobile networks. While fixed networks benefit from lower unit costs ($0.06/GB vs. $0.33/GB for mobile), far higher household data consumption drives a 393% higher TCO per subscriber ($21.22 vs. $5.40). A small set of applications accounts for the vast majority of costs: 9 apps drive 92% of fixed expenses and seven drive 96% of mobile led by YouTube, Netflix, TikTok, Facebook, and Steam. Cost burdens are concentrated in the access layer for fixed networks (75% of TCO) and in the RAN for mobile (85%), underscoring structural vulnerabilities as video, gaming, and latency-sensitive applications proliferate.For CSPs, these dynamics create rising margin pressure, which are exacerbated by OTT players that capture revenue while operators absorb infrastructure costs. To respond, CSPs must adopt application-aware traffic management to optimize QoE and defer CapEx, pursue commercial or regulatory frameworks to rebalance costs with OTT providers, and deploy CSP specific TCO models to guide investment and policy strategies. Sustaining profitability in an application-centric era will depend on combining smarter traffic engineering, fairer cost sharing, and tailored economic modeling.Download report:https://www.acgcc.com/reports/the-economics-of-application-traffic-tco-benchmark/ For more information, contact Ray Mota or Peter Fetterolf.
