The Quantum Computing Podcast with Fexingo: Qubits, Quantum Hardware, and Future Computing

Fexingo

This is a podcast about the current state and near-term future of quantum computing. Lucas and Luna examine the science and business of quantum hardware, from superconducting qubits to trapped ions and topological systems. They discuss the engineering challenges of error correction, the race to quantum supremacy, and the realistic timelines for commercial quantum advantage. Each episode focuses on a specific company, research paper, or technology milestone — Google's Sycamore, IBM's Quantum System One, IonQ's trapped-ion processors, or China's quantum communication network. Lucas brings a journalist's rigor to the technical details, while Luna pushes for clarity on what these advances mean for cryptography, drug discovery, optimization, and finance. This show is for listeners who want to understand quantum computing without hype — the real bottlenecks, the credible roadmaps, and the startups that might actually deliver. How close are we to a fault-tolerant quantum computer? Which industries will be transformed first? And which approaches are likely dead ends? #QuantumComputing #Qubits #QuantumHardware #QuantumSupremacy #ErrorCorrection #SuperconductingQubits #TrappedIons #TopologicalQubits #GoogleSycamore #IBMQuantum #IonQ #QuantumCryptography #DrugDiscovery #Optimization #Technology #Business #FexingoBusiness #BusinessPodcast Keep every episode free: buymeacoffee.com/fexingo

    Quantum Error Correction The Real Bottleneck

    We look at why building a useful quantum computer is less about adding qubits and more about fixing their mistakes. We explore the surface code, the overhead of physical versus logical qubits, and what that means for timelines in late twenty twenty six.
