## Resource

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.
