For the first time, Shor’s Algorithm is running on logical qubits! The team at Infleqtion used their Sqale neutral atom processor to accomplish the feat. While the setup only uses six logical qubits, and we’re still in the range of factoring 15 or 21, this is both a proof of concept and a proof of the need for post-quantum cryptography (PQC). We discuss the aggressive 2.5:1 physical-to-logical ratio of Sqale, which could lead to hundreds of logical qubits by 2028. Also, find out why Shor’s Algorithm could surprisingly end up being one of the first killer apps for quantum computing, rather than a later use case. Join host Konstantinos Karagiannis for a wide-ranging chat with Peter Noell from Infleqtion. For more information on Infleqtion, visit https://infleqtion.com/.

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.
