Slashing the Time to Quantum Advantage – with Toby Cubitt of Phasecraft
What if the timelines for world-changing quantum computing aren’t dictated only by hardware manufacturers, but also by the sheer power of a better idea? In this episode, host Konstantinos Karagiannis sits down with Toby Cubitt, the co-founder and CTO of Phasecraft, to explore how clever mathematics and algorithmic breakthroughs are slashing the requirements for quantum advantage by orders of magnitude. Toby shares how his team has already knocked factors of one million off the gate counts for critical simulations, effectively buying a decade of hardware development through pure software innovation. Q-Day and the shifting goalposts of breaking RSA encryption are a reality, but the discussion also covers revolutionizing the very materials that power our batteries and industrial catalysts.Beyond the technical benchmarks, Toby pulls back the curtain on the Wild West era of quantum computing, drawing fascinating parallels to the vacuum tubes and mercury delay lines of the 1950s. He also moves on to myths such as: Will AI make quantum computing obsolete? Can you actually run ChatGPT on a quantum processor? Whether you are a business leader looking to "Nitro-inject" your classical optimization workflows or a science enthusiast eager to hear from a world expert who has access to every major quantum machine on the planet (from Google’s Willow chip to IBM and Quantinuum) this episode is a hype-free must.

Quantum Vibe Coding – with Vincent van Wingerden of Classiq
How do you go from a quantum computing research paper to a circuit you can run on a real machine? Can AI help bridge the gap between complex mathematical theory and functional quantum code? In this episode, Vincent van Wingerden, Director of Strategic Partnerships at Classiq, joins host Konstantinos Karagiannis to discuss the dawn of quantum vibe coding. While traditional quantum programming often requires tedious manual manipulation of gates and hardware-specific constraints, Classiq’s platform introduces a high-level abstraction that allows users to focus on intent rather than implementation. Vincent explains how their AI-driven assistant, powered by Claude, can ingest an academic paper from arXiv and generate a working implementation in minutes, a task that once took experts weeks of effort. Beyond the vibe, this episode dives into the practical mechanics of how Classiq’s compiler optimizes code across diverse hardware modalities, from IonQ to IBM. You’ll hear about real-world collaborations with Comcast and AMD, as well as a fascinating example of how an AI agent suggested improvements to an image-edge-detection algorithm that outperformed its original human design. Whether you are a seasoned computer scientist or a curious beginner looking to bypass the gate-level barrier, this conversation reveals how the synergy between high-level languages and AI is dismantling the quantum talent gap and scaling the industry toward the future.

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.

PQC Job Market Soaring and the Year of Quantum Seriousness – with YouTuber Addie LaMarr
In this landmark five-year special episode, host Konstantinos Karagiannis welcomes Addie LaMarr, a YouTuber and former cryptographer with eight years of experience in the Air Force and a history of writing cybersecurity policy for the Department of Justice. LaMarr identifies 2026 as the “beginning of quantum seriousness,” a year where global regulations are forcing a transition to protect critical data longevity from a growing tsunami of threats. Drawing from her military background, she emphasizes that cryptography is often a matter of life and death, sharing a sobering example of “Identify Friend or Foe” systems where a single cryptographic error can cause an aircraft to be treated as a hostile target.The conversation also explores the strategic and societal shifts required as quantum computing matures. LaMarr argues that now is the optimum time for cybersecurity professionals to pivot into post-quantum cryptography (PQC) specialization, noting that such a move could yield pay bumps similar to those who transitioned to AI jobs. However, she pairs this optimism with a warning about how massive computational power could be used to build digital twins and manipulate autonomy. Finally, she cautions that the world may not receive a formal warning when Q-Day arrives, as nations will likely hide their quantum breaking capabilities to maintain informational dominance, much like the secrecy surrounding the cracking of the Enigma code in World War II.For more information on Addie LaMarr, visit www.addielamarr.com/.

The Fall and Rise of a Quantum Company Boosting Algorithmic Development – with Sumit Kapur of Zapata Quantum
Zapata’s back! A tough stretch including a difficult SPAC deal, a brief move into AI, and a $20 million debt forced the company to shut down in 2024. But in this episode, Sumit Kapur, CEO of Zapata Quantum, talks with host Konstantinos Karagiannis about how the company made a remarkable comeback. They discuss the intense restructuring, the strong support from the quantum computing industry, and how Zapata’s seven years of intellectual property proved too valuable to give up.The conversation goes into the prospects of quantum utility, focusing on Quantum Intermediate Representation (QIR)—a universal translator that abstracts the immense complexity of hybrid computing. Sumit explains why the industry is entering a critical arms race for application intelligence and why even skeptics are now predicting that milestones like Shor’s algorithm could be achieved far sooner than previously imagined. From collaborating with DARPA on quantum benchmarking to finding the company’s new north star in a post-SPAC world, this episode showcases resilience plus a forward-looking roadmap for the next decade of quantum edge.For more information on Zapata Quantum, visit https://zapataquantum.com/.

Q-Day 10x Closer Than We Thought—Pinnacle Paper Accelerates RSA Factoring — with Felix Thomsen and Paul Webster of Iceberg Quantum
The groundbreaking Pinnacle Architecture paper has sent shockwaves through the quantum computing industry by demonstrating that RSA-2048 encryption could potentially be cracked with just 100,000 physical qubits. This is a massive order-of-magnitude reduction from previous estimates that once reached into the millions. Join host Konstantinos Karagiannis as he sits down with Felix Thomsen and Paul Webster from Iceberg Quantum as they explain the techniques in the paper and its serious potential ramifications. By leveraging high-efficiency LDPC codes and a novel modular architecture, the team explains how they’ve bridged the gap between theoretical quantum error correction and practical hardware implementation, effectively accelerating the timeline toward Q-Day. More than one quantum computing hardware roadmap has us reaching 100,000 physical qubits before 2030! And there’s no reason to believe future work couldn’t lower the qubit requirements even more. Beyond the security implications, the architecture is also a blueprint for the first generation of utility-scale quantum systems. Thomsen and Webster detail how their modular design—featuring dedicated processing units, magic engines, and shared memory—can be optimized for “slow” hardware like trapped ions or applied to life-changing scientific breakthroughs in quantum chemistry and material science. Whether you are a cryptographer bracing for the post-quantum transition or a scientist eager to see the first practical applications of fault-tolerant quantum computing, you’ll need to understand this paper’s potential impact.

Quantum Money and Self-Destructing Signatures — with NTT
A one-shot signature is a new quantum computing tool that lets people verify information publicly using a quantum signing key that destroys itself after use. This “proof of destruction” makes sure the key can only be used once, which could lead to cryptographic solutions that classical math could not achieve. Host Konstantinos Karagiannis talks with Omri Shmueli, a cryptographer and postdoctoral research fellow at NTT Research, about how one-shot signatures might change digital finance and secure communication. Shmueli shares how this technology could make decentralized cryptocurrency possible without a blockchain or help solve the big scalability problems of current blockchains by letting users create their own unique quantum money. The episode also looks at how unclonable quantum keys could give users proof that not only do they have a secret key, but they are the only person in the world who does.
