    Overview

    In this episode of The Brand Called You (TBCY) podcast, host Stephen Ibaraki speaks with Théau Peronnin, Co-founder and CEO of Alice & Bob, one of Europe’s most promising quantum computing startups.

    Théau shares his journey from an early passion for physics to building a company focused on solving one of quantum computing’s greatest challenges: fault tolerance. The discussion explores how Alice & Bob’s pioneering cat qubit architecture dramatically reduces error rates and the number of physical qubits required—bringing scalable, practical quantum computing closer to reality.

    This episode blends deep science with entrepreneurship, explaining complex ideas in an accessible way while highlighting how foundational research can be transformed into real-world impact.

    Early Journey into Quantum Science
    • Early exposure to science, electronics, and competitive physics
    • Participation in the International Young Physicist Tournament
    • Attraction to open-ended problems and scientific debate
    • Inspiration from Nobel Prize–winning research
    • Entrepreneurial mindset shaped by family business discussions
      • Why Fault-Tolerant Quantum Computing Matters
      • Shift from NISQ systems to logical, fault-tolerant qubits
      • Traditional approaches require massive redundancy
      • Cat qubits introduce a radically more efficient design
        • What Are Cat Qubits?
        • A specialized form of superconducting qubits
        • Inspired by Schrödinger’s cat thought experiment
        • Encode information in superpositions of near-classical states
        • Naturally suppress bit-flip errors at the hardware level
          • Performance, Economics, and Scalability
          • Cat qubits dramatically reduce error-correction overhead
          • Up to 200× fewer physical qubits needed for the same reliability
          • Enables faster scaling and improved capital efficiency
          • Opens doors to applications in materials science, finance, and pharma
            • Ecosystem and Industry Momentum
            • Partnership with NVIDIA to develop open-source quantum middleware
            • Focus on software abstraction and developer accessibility
            • Increasing convergence of hardware, software, and enterprise adoption
