The Post-Quantum World

Is quantum technology purely a science of the future, or can it solve major enterprise problems today? In this episode, Pouya Dianat, Chief Revenue Officer of Quantum Computing Inc. (QCi), joins host Konstantinos Karagiannis to discuss how his company is moving past the lab stage to deliver real business value right now. Dianat breaks down QCi’s unique hardware approach using nonlinear photonics and thin-film lithium niobate, explaining why the company has focused on application-specific, analog quantum optimization machines rather than waiting for universal gate-based systems to mature in the 2030s. 
  
The conversation dives deep into QCi's latest breakthrough algorithm, CVQBoost, which leverages the physics of their Dirac 3 system to revolutionize financial fraud detection. Operating literally at the speed of light, this room-temperature, rack-mountable quantum computer eliminates classical processing bottlenecks and effortlessly bypasses the training limitations that plague traditional GPUs. Dianat also shares insights into how recent federal executive orders on quantum technology are impacting the sales landscape, QCi’s cutting-edge quantum authentication solutions for network security, and his strategic vision for driving immediate commercial revenues while advancing a long-term quantum roadmap.

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.

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.

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.

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.
