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 #Topologi…","last_synced_at":"2026-06-20T20:22:02.827480+00:00","page_url":"https://stenobird.com/podcast/the-quantum-computing-podcast-with-fexingo-qubits-quantum-hardware-and-future-computing-7871946"},"episode":{"title":"Quantum Error Correction Is Becoming Practical at Last","slug":"quantum-error-correction-is-becoming-practical-at-last","published_at":"2026-06-15T20:47:05+00:00","page_url":"https://stenobird.com/podcast/the-quantum-computing-podcast-with-fexingo-qubits-quantum-hardware-and-future-computing-7871946/quantum-error-correction-is-becoming-practical-at-last","show_page_url":"https://stenobird.com/podcast/the-quantum-computing-podcast-with-fexingo-qubits-quantum-hardware-and-future-computing-7871946","url":"https://audio.fexingo.com/business/the-quantum-computing-podcast/episode-0053.mp3","audio_url":"https://audio.fexingo.com/business/the-quantum-computing-podcast/episode-0053.mp3","summary":"In episode 53 of The Quantum Computing Podcast with Fexingo, Lucas and Luna explore a breakthrough that's quietly shifting quantum computing from theoretical promise toward practical reality: error correction that actually works at scale. We dive into Google's recent demonstration of a logical qubit with error rates below the surface-code threshold—a milestone that many researchers thought was years away. We explain what a logical qubit is, why error correction has been the field's 'final boss,' and how Google's team used a 17-qubit superconducting processor to encode one reliable qubit. Lucas breaks down the math: physical qubit error rates near 0.1 percent, logical error rates around 0.03 percent. Luna questions whether this can scale to the thousands of logical qubits needed for useful algorithms. We also look at parallel work from IBM and Quantinuum on alternative codes. If you've been waiting for quantum computing to deliver on its hype, this episode explains why error correction might finally be the unlock. #QuantumComputing #ErrorCorrection #GoogleQuantum #LogicalQubit #SurfaceCode #IBMQuantum #Quantinuum #Qubits #QuantumTechnology #Technology #FexingoBusiness #BusinessPodcast #Podcast #Fexingo #LucasAndLuna #QuantumBreakthrough #SuperconductingQubits #QuantumScaling Keep every episode free: buymeacoffee.com/fexingo","meta_description":"In episode 53 of The Quantum Computing Podcast with Fexingo, Lucas and Luna explore a breakthrough that's quietly shifting quantum computing from theoreti…","key_points":[],"chapters":[],"topics":[],"duration_seconds":584,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/the-quantum-computing-podcast-with-fexingo-qubits-quantum-hardware-and-future-computing-7871946/episodes/quantum-error-correction-is-becoming-practical-at-last/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/the-quantum-computing-podcast-with-fexingo-qubits-quantum-hardware-and-future-computing-7871946/quantum-error-correction-is-becoming-practical-at-last.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
