The Post-Quantum World

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 Source traps single rubidium atoms inside tiny glass vacuum cavities to act as direct go-betweens, cleanly entangling passing photons on demand without requiring massive cryogenic setups or impossibly identical light pulses. Prof. Dayan, who literally holds up the hardware resonator during the conversation (if you watch on YouTube), explains how this approach acts like an ultra-fast quantum sewing machine, weaving qubits together in nanoseconds to enable modular, rack-based scaling. Discover how this unique hardware design tackles error correction, unlocks flexible long-range connectivity, and targets a fully fault-tolerant logical qubit by 2029.    For more on Quantum Source, visit https://www.qs-labs.com/. Visit Protiviti at www.protiviti.com/US-en/technology-consulting/quantum-computing-services to learn more about how Protiviti is helping organizations get post-quantum ready.  Follow host Konstantinos Karagiannis on all socials: @KonstantHacker             Questions and comments are welcome!  Theme song by David Schwartz, copyright 2021.  The views expressed by the participants of this program are their own and do not represent the views of, nor are they endorsed by, Protiviti Inc., The Post-Quantum World, or their respective officers, directors, employees, agents, representatives, shareholders, or subsidiaries.  None of the content should be considered investment advice, as an offer or solicitation of an offer to buy or sell, or as an endorsement of any company, security, fund, or other securities or non-securities offering.

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.   At the center of this breakthrough is Orbit, Quantum Elements’ error-suppression function. Medalsy breaks down how Orbit uses precise dynamical decoupling to actively stabilize idle qubits and protect dynamic, branching circuits without altering the underlying gate structure. It even takes error suppression into the logical qubit realm. Paired with AI-trained digital twins and a shared roadmap pointing toward fault-tolerant systems like IBM Starling, Panda and Medalsy deliver an inside look at how AI workflows, modular software, and hybrid error management are unlocking real scientific utility today.   For more on IBM Quantum, visit https://www.ibm.com/quantum.   For more on Quantum Elements, visit https://quantumelements.ai/.Visit Protiviti at www.protiviti.com/US-en/technology-consulting/quantum-computing-services to learn more about how Protiviti is helping organizations get post-quantum ready.  Follow host Konstantinos Karagiannis on all socials: @KonstantHacker             Questions and comments are welcome!  Theme song by David Schwartz, copyright 2021.  The views expressed by the participants of this program are their own and do not represent the views of, nor are they endorsed by, Protiviti Inc., The Post-Quantum World, or their respective officers, directors, employees, agents, representatives, shareholders, or subsidiaries.  None of the content should be considered investment advice, as an offer or solicitation of an offer to buy or sell, or as an endorsement of any company, security, fund, or other securities or non-securities offering.

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.Beyond the physics, Grundmann explores why on-prem, rack-mounted quantum hardware is a potential gamechanger for industries handling mission-critical data. From analyzing ultra-sensitive patient medical records completely offline to scaling parallel workloads across multi-processor architectures, he shares how accessible semiconductor manufacturing methods could finally take quantum out of deep-freeze science labs and drive it toward consumer-level pricing.For more on SAXON Q, visit https://www.saxonq.com/.Visit Protiviti at www.protiviti.com/US-en/technology-consulting/quantum-computing-services to learn more about how Protiviti is helping organizations get post-quantum ready.  Follow host Konstantinos Karagiannis on all socials: @KonstantHacker             Questions and comments are welcome!  Theme song by David Schwartz, copyright 2021.  The views expressed by the participants of this program are their own and do not represent the views of, nor are they endorsed by, Protiviti Inc., The Post-Quantum World, or their respective officers, directors, employees, agents, representatives, shareholders, or subsidiaries.  None of the content should be considered investment advice, as an offer or solicitation of an offer to buy or sell, or as an endorsement of any company, security, fund, or other securities or non-securities offering.

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.   Beyond hardware breakthroughs, the conversation tackles the urgent inflection point facing enterprise and public sector leaders. Chehreh details why executive orders and looming cryptographic deadlines mean organizations cannot treat post-quantum cryptography migration as standard IT patching. From real-world defense war-gaming and energy sector hybrid CPU-GPU-QPU pipelines to the complementary deployment of QKD and PQC, this episode delivers a high-stakes look at how quantum computing is leaving the laboratory to reshape modern infrastructure and AI workloads.   For more on IonQ, visit https://www.ionq.com/.Visit Protiviti at www.protiviti.com/US-en/technology-consulting/quantum-computing-services to learn more about how Protiviti is helping organizations get post-quantum ready.  Follow host Konstantinos Karagiannis on all socials: @KonstantHacker             Questions and comments are welcome!  Theme song by David Schwartz, copyright 2021.  The views expressed by the participants of this program are their own and do not represent the views of, nor are they endorsed by, Protiviti Inc., The Post-Quantum World, or their respective officers, directors, employees, agents, representatives, shareholders, or subsidiaries.  None of the content should be considered investment advice, as an offer or solicitation of an offer to buy or sell, or as an endorsement of any company, security, fund, or other securities or non-securities offering.

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.  For more on EigenQ, visit https://www.eigenq.com/.Visit Protiviti at www.protiviti.com/US-en/technology-consulting/quantum-computing-services to learn more about how Protiviti is helping organizations get post-quantum ready.  Follow host Konstantinos Karagiannis on all socials: @KonstantHacker             Questions and comments are welcome!  Theme song by David Schwartz, copyright 2021.  The views expressed by the participants of this program are their own and do not represent the views of, nor are they endorsed by, Protiviti Inc., The Post-Quantum World, or their respective officers, directors, employees, agents, representatives, shareholders, or subsidiaries.  None of the content should be considered investment advice, as an offer or solicitation of an offer to buy or sell, or as an endorsement of any company, security, fund, or other securities or non-securities offering.
