Q-Day 10x Closer Than We Thought—Pinnacle Paper Accelerates RSA Factoring — with Felix Thomsen and Paul Webster of Iceberg Quantum
The Post-Quantum WorldShow Notes
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.

Most quantum computing modalities face difficult hurdles with connectivity and scaling. Trapped atoms are great at interacting to run quantum calculations, but connecting millions of them together can be an engineering challenge. Photons are fantastic for fast communication and can link systems through standard fiber-optic cables, but because they pass right through one another without touching, getting them to interact and perform quantum gates usually requires massive, complex workarounds. In this episode, Professor Barak Dayan, Chief Scientist and Co-Founder of Quantum Source, joins host Konstantinos Karagiannis to explain how combining the two creates a completely new kind of quantum computer: a hybrid atom-photon machine that captures the best of both.
Quantum computing is rapidly crossing the chasm from low-level physics experiments to practical, enterprise-grade problem-solving. In this episode, host Konstantinos Karagiannis sits down with IBM Quantum Product Lead Sanket Panda and Quantum Elements CEO Izhar Medalsy to uncover how the modern Qiskit ecosystem is stripping away hardware complexity. From Qiskit’s core Rust rewrite slashing transpilation times from an hour to mere milliseconds, to the introduction of modular Qiskit Functions, the conversation reveals how high-performance software engineering is enabling researchers to focus strictly on domain discovery, such as chemistry and optimization, rather than circuit tuning.
Quantum computing has long been trapped inside massive dilution refrigerators, but SAXON Q is looking to change that. CEO Marius Grundmann joins host Konstantinos Karagiannis breaks down how his company uses artificial diamond chips and atomic-scale NV centers to build fully functional, room-temperature quantum computers that mount directly into standard 19-inch server racks. By leveraging the natural rigidity of diamond crystals to protect delicate nuclear and electron spin qubits from ambient thermal noise, SAXON Q delivers a resilient system capable of running live in data centers without complex cryogenic overhead.
IonQ’s VP of Engineering and CTO, Cameron Chehreh, joins host Konstantinos Karagiannis to break down why the race to scalable quantum computing is accelerating far faster than expected. Bringing a pragmatic, classical compute mindset to quantum systems, Chehreh explains how IonQ is transitioning from traditional optical tables to chip-scale trapped-ion QPUs, bolstered by their SkyWater foundry acquisition to dramatically speed up silicon iteration. He also provides an exclusive update on the company’s hardware roadmap, confirming that their 256-qubit system is currently in fabrication and on track as they march toward 10,000 qubits and cryptographically relevant scale before 2030.
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.
