Preventing Some PQC Rip-and-Replace – with José Rosas of EigenQ

The quantum computing threat isn't a far-off problem anymore, with deadlines rapidly shifting closer to 2029. Organizations are scrambling to secure $30 trillion in legacy IT infrastructure. Dr. José Rosas, CEO of EigenQ, joins host Konstantinos Karagiannis to explain how his company can bypass the need for costly "rip-and-replace" server upgrades by delivering plug-and-play PCIe accelerator boards. By combining quantum entropy (random number generation) with post-quantum cryptography (PQC) algorithms into existing server architectures like Intel Xeon and AMD EPYC, EigenQ creates a full-stack, hardware-rooted trust layer without modifying host motherboards. Beyond retrofitting legacy servers, Dr. Rosas reveals EigenQ's broader vision to master crypto-agility. Using dynamic hardware reconfiguration to adapt as PQC standards evolve prevents getting trapped by rigid silicon designs. He delves into how their hardware integrates directly into CPU Trusted Execution Environments (TEEs), extends to tactical edge environments like drones, and lays the groundwork for their next frontier: quantum-assisted AI and photonic interconnects.

Building the “Worst” Quantum Devices at DEF CON – with Mark Carney and Victoria Kumran of Quantum Village

In this episode, host Konstantinos Karagiannis reunites with longtime friends and co-founders of the Quantum Village, Mark Carney and Victoria Kumran, to preview their upcoming plans for DEF CON 34. Celebrating their fifth anniversary, the duo reflects on how the Quantum Village has evolved from a "hodgepodge" of quantum skepticism into an internationally recognized hub for open-source, hands-on hardware. Backed by their first-ever philanthropic grant from Mozilla, Victoria and Mark highlight how the village is breaking down academic barriers and empowering educators, security researchers and hobbyists alike to engage with complex quantum concepts on their own terms. Get an exciting look at some of the village's wildest DIY achievements, including a recap of "Uncut Gem," a budget-friendly, open-source quantum magnetometer built using green LEDs and red filter gel instead of expensive laboratory lasers. They also dive into their newest $35 open-source creation, the "entropy loop," a quantum random number generator (QRNG) designed to build real intuition about vacuum fluctuations and phase diffusion. Touching on this year's DEF CON theme of "agency," the guests tackle how independent creators can push back against big-tech opacity by building and understanding their own secure systems. As with DEF CON in general, this episode covers a wide technical range, from how quantum sensors might detect alien signals to tinkering with a Raspberry Pi Pico.

1000x Faster and Cheaper – with Richard Givhan of Haiqu

Is quantum computing trapped behind a hardware bottleneck? In this episode, host Konstantinos Karagiannis sits down with Richard Givhan, the CEO of Haiqu, who challenges this long-standing narrative. While the industry has historically focused on building perfect, fault-tolerant systems, Givhan argues that this theoretical cynicism has caused the software layer to be deeply undervalued. Haiqu is disrupting this perspective by championing a wave of empirical optimism, proving that enterprise R&D teams can extract massive value, run frontier-scale simulations, and achieve scientific milestones right now using near-term, noisy, and partially corrected hardware. The conversation dives deep into Haiqu’s breakthrough orchestration and compression techniques, demonstrating how they achieved a jaw-dropping 1,000x reduction in both time and cost. Specifically, they compressed a $30,000, nine-hour QPU simulation down to just $25 and 30 seconds. Givhan also unveils the future of the quantum workflow: Haiqu's agentic Quantum OS. By integrating specialized AI research agents to automate literature reviews, handle classical baselining, and collaboratively design advanced circuits, Haiqu is dramatically accelerating the R&D loop from six-month trial phases down to a matter of days. Finally, Givhan shares his perspective on the true arrival of commercial quantum advantage, noting that we will know it is truly here when competitive industries, like finance, suddenly go completely silent about their quantum capabilities.

The Race to Save Bitcoin – with Chris Tam of BTQ

Is the ultimate cryptocurrency ticking toward a sudden, quantum-powered collapse? In this episode, Chris Tam, President and Head of Innovation at BTQ, joins host Konstantinos Karagiannis to shatter the comforting illusions many Bitcoiners still hold about the quantum computing threat. While many assume that a Q-Day attack would only disrupt future mining, Tam exposes the true, terrifying reality: Quantum computers utilizing Shor's algorithm are on an exponential trajectory to cracking the elliptic curve cryptography that safeguards individual wallets. Even worse, recent upgrades like Taproot have inadvertently introduced more vulnerable public keys into the ecosystem, making a network upgrade more complex than ever. The real crisis isn't just finding a cryptographic fix: it's time. Experts warn that migrating the entire decentralized Bitcoin network to a post-quantum standard could take upwards of seven years, but the network simply lacks the block space to move everyone before quantum adversaries are predicted to break the encryption. To bypass the political gridlock of Bitcoin core development, Tam details how BTQ surgically built a working, post-quantum Bitcoin Quantum testnet to experiment with solutions like BIP 360 in the real world. From the catastrophic ripple effects a Bitcoin hack would have on traditional financial markets to BTQ’s pioneering work on day-one quantum-resistant stablecoins in South Korea, this episode is an urgent, eye-opening wake-up call for anyone holding digital assets.

NVIDIA Architect Warns We Might Need to Rip and Replace Hardware for PQC – with TCG

Quantum technical debt is the idea that some devices cannot be upgraded to PQC. In this episode, Thorsten Stremlau, a Systems Principal Architect at NVIDIA and Co-Chair of the Trusted Computing Group (TCG) Marketing Work Group, joins host Konstantinos Karagiannis to discuss the critical role of hardware roots of trust in protecting against the quantum computing threat. Stremlau outlines the challenges of integrating heavier PQC algorithms into resource-constrained chips like the Trusted Platform Module (TPM), highlighting technical hurdles such as increased computational intensity, memory bloat, and heightened vulnerability to side-channel and denial-of-service attacks. To counter these quantum threats while maintaining historical stability, the TCG has released the TPM 2.0 library version 1.85 paired with the platform specification 107. This combination leverages built-in crypto-agility to implement mature algorithms like ML-KEM and ML-DSA, while still supporting hybrid classical-quantum models to ensure a smoother migration path for enterprises. However, Stremlau issues a stark warning regarding the industry's timeline and the reality of quantum technical debt, revealing that achieving full PQC readiness will require a complete hardware replacement rather than simple in-field firmware updates. Government entities are aggressively mandating PQC compliance for procurement by 2027. But the enterprise sector, particularly critical infrastructure and server environments, faces an incredibly long transition cycle due to a traditional preference for operational stability over rapid upgrades. While a PQC-ready TPM is a foundational piece of the puzzle that secures firmware signing, boot processes and platform attestation, it is not a silver bullet. True quantum resilience requires a defense-in-depth strategy where the entire software and data ecosystem, including AI workloads, edge networks and data pipelines, is systematically upgraded alongside the hardware foundation.

Computing on PQC-Encrypted Data – with Dr. Kurt Rohloff of Duality Technologies

What if you could crunch numbers on a dataset without ever actually seeing the sensitive information inside? Dr. Kurt Rohloff, co-founder and CTO of Duality Technologies, joins host Konstantinos Karagiannis to explain the wild capabilities of Fully Homomorphic Encryption (FHE), which allows for computation on data while it remains fully encrypted. Because FHE is built on lattice-based cryptography, it offers robust post-quantum security properties right out of the box. Learn how this technology provides end-to-end protection not just for data at rest or in motion, but for data in use. FHE effectively turns the cloud into a secure processing powerhouse where privacy will remain uncompromised even after the threat of quantum computing arrives. From revolutionizing rare disease research by aggregating data across global medical centers to identifying international financial criminals without exposing private bank records, the real-world applications Rohloff describes are staggering. He discusses how Duality is replacing months of legal red tape and NDAs with "cup of coffee time" queries and pushing the boundaries of AI by protecting sensitive Large Language Model (LLM) workloads. Whether you're interested in the open-source OpenFHE library or the future of hardware-accelerated privacy, this episode is a deep dive into how we can democratize science and secure the AI tech stack for a post-quantum era.
