We will cover topics in quantum computing, networking and sensing, focusing on hardware, algorithms and general theory. The show aims for accessibility - Sebastian is not a physicist - and we'll try to provide context for the terminology and glimpses at the fascinating history of this new field as it evolves in real time.","last_synced_at":"2026-07-28T06:19:15.608488+00:00","page_url":"https://stenobird.com/podcast/the-new-quantum-era-innovation-in-quantum-computing-science-and-technology-5609388"},"episode":{"title":"Macroscopic Quantum Tunneling with Nobel Laureate John Martinis","slug":"macroscopic-quantum-tunneling-with-nobel-laureate-john-martinis","published_at":"2025-11-26T15:39:09+00:00","page_url":"https://stenobird.com/podcast/the-new-quantum-era-innovation-in-quantum-computing-science-and-technology-5609388/macroscopic-quantum-tunneling-with-nobel-laureate-john-martinis","show_page_url":"https://stenobird.com/podcast/the-new-quantum-era-innovation-in-quantum-computing-science-and-technology-5609388","url":"https://newquantumera.transistor.fm/71","audio_url":"https://op3.dev/e/dts.podtrac.com/redirect.mp3/media.transistor.fm/2c6696b8/325cf5f4.mp3","summary":"Episode overview John Martinis, Nobel laureate and former head of Google’s quantum hardware effort, joins Sebastian Hassinger on The New Quantum Era to trace the arc of superconducting quantum circuits—from the first demonstrations of macroscopic quantum tunneling in the 1980s to today’s push for wafer-scale, manufacturable qubit processors. The episode weaves together the physics of “synthetic atoms” built from Josephson junctions, the engineering mindset needed to turn them into reliable computers, and what it will take for fabrication to unlock true large-scale quantum systems. Guest bio John M. Martinis is a physicist whose experiments on superconducting circuits with John Clarke and Michel Devoret at UC Berkeley established that a macroscopic electrical circuit can exhibit quantum tunneling and discrete energy levels, work recognized by the 2025 Nobel Prize in Physics “for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric circuit.” He went on to lead the superconducting quantum computing effort at Google, where his team demonstrated large-scale, programmable transmon-based processors, and now heads Qolab (also referred to in the episode as CoLab), a startup focused on advanced fabrication and wafer-scale integration of superconducting qubits. Martinis’s career sits at the intersection of precision instrumentation and systems engineering, drawing on a scientific “family tree” that runs from Cambridge through John Clarke’s group at Berkeley, with strong theoretical influence from Michel Devoret and deep exposure to ion-trap work by Dave Wineland and Chris Monroe at NIST. Today his work emphasizes solving the hardest fabrication and wiring challenges—pursuing high-yield, monolithic, wafer-scale quantum processors that c…","meta_description":"Episode overview John Martinis, Nobel laureate and former head of Google’s quantum hardware effort, joins Sebastian Hassinger on The New Quantum Era to tr…","key_points":[],"chapters":[],"topics":[],"duration_seconds":2966,"processing_state":"not_requested","actions":[{"name":"request_transcript","method":"POST","url":"https://stenobird.com/v1/public/podcasts/the-new-quantum-era-innovation-in-quantum-computing-science-and-technology-5609388/episodes/macroscopic-quantum-tunneling-with-nobel-laureate-john-martinis/transcription-requests","description":"Idempotently request low-priority transcript generation for this episode."},{"name":"read_markdown","method":"GET","url":"https://stenobird.com/podcast/the-new-quantum-era-innovation-in-quantum-computing-science-and-technology-5609388/macroscopic-quantum-tunneling-with-nobel-laureate-john-martinis.md","description":"Read the agent-friendly Markdown representation of this episode resource."}]}}
