Why Do Quantum Computers Make So Many Mistakes? | Mikhail Lukin on Quantum Error Correction

Why do civilizations rise, prosper, and then collapse? Here's what the math tells us.In this episode, we sit down with Peter Turchin, complexity scientist and founder of the field of cliodynamics, which uses data and mathematical models to study the long-term cycles of history. Turchin explains his theory of elite overproduction, how societies generate too many ambitious, educated elites competing for too few positions, and why this dynamic reliably leads to polarization, inequality, and political turmoil.We explore how his structural-demographic theory maps the recurring “boom and bust” rhythms that have shaped civilizations from ancient Rome to modern America, the role of military competition in driving cooperation and social complexity, and how new tools—from AI-assisted historical databases to ancient DNA and LiDAR—are transforming the study of the past.Whether you’re drawn to history, sociology, complexity science, or the fate of modern democracies, this conversation reveals how Turchin’s quantitative approach offers a new way to understand—and maybe even forecast—the forces that make societies rise and fall.Follow us for more technical interviews with the world’s greatest scientists:Twitter: https://x.com/632nmPodcastInstagram: https://www.instagram.com/632nmpodcast?utm_source=ig_web_button_share_sheet&igsh=ZDNlZDc0MzIxNw==LinkedIn: https://www.linkedin.com/company/632nm/about/Substack: https://632nmpodcast.substack.com/Follow our hosts!Michael Dubrovsky: https://x.com/MikeDubrovskyMisha Shalaginov: https://x.com/MYShalaginovXinghui Yin: https://x.com/XinghuiYinSubscribe:Apple Podcasts: https://podcasts.apple.com/us/podcast/632nm/id1751170269Spotify: https://open.spotify.com/show/4aVH9vT5qp5UUUvQ6Uf6ORWebsite: https://www.632nm.comTimestamps:00:00 - Intro01:48 - Overproduction of Elites10:56 - Did Models Predict the Rise of Trump?20:43 - Is Russian History Repeating in the US?26:48 - How Competition Stabilizes Societies32:14 - What Data Goes into Cliodynamic Models?38:13 - How New Technologies Shaped Archaeology43:28 - Can Historians Build Mathematical Intuitions?47:59 - What Questions can be Answered with Cliodynamics?52:23 - Does the NYC Mayoral Race Fit into Turchin's Theory?56:37 - Is Fear of China Bringing Us Together?58:29 - Do Historians Reject Turchin’s Work?1:00:03 - Trends in Civilizations and Outliers1:03:29 - Calvary and the Evolution of Societies1:10:03 - Is Evolution via Natural Selection a Suitable Analog for History?1:15:16 - Could Turchin's Ideas Be Misinterpreted Dangerously?

Science has stalled. And Adam Marblestone thinks he knows why.Check out the Research Gap Map here: https://www.gap-map.org/?sort=rankIn this episode, we sit down with Adam Marblestone, neuroscientist, nanotechnologist, and founder of Convergent Research, to explore how new “Focused Research Organizations” (FROs) could reignite scientific progress. From DNA “ticker-tape” neural recording to optical connectomics and Neuralink, Marblestone explains how emerging neurotechnologies reveal both the brilliance and the bottlenecks of today’s research system.We discuss why traditional funding often fails to support ambitious, interdisciplinary projects, how FROs borrow the focus and speed of startups to build scientific infrastructure, and why projects like OpenAI, E11 Bio, and ultrasound-on-a-chip exemplify this new model. Marblestone breaks down his “Gap Map” of unsolved scientific challenges - from room-temperature superconductors to artificial ribosomes - and does the math on how tens of billions of dollars could close them.Whether you’re fascinated by neuroscience, scientific innovation, or the future of research itself, this conversation offers a rare insider’s look at how new institutions could rebuild the engine of discovery—and why the next wave of breakthroughs might depend more on organization than on ideas.Follow us for more technical interviews with the world’s greatest scientists:Twitter: https://x.com/632nmPodcastInstagram: https://www.instagram.com/632nmpodcast?utm_source=ig_web_button_share_sheet&igsh=ZDNlZDc0MzIxNw==LinkedIn: https://www.linkedin.com/company/632nm/about/Substack: https://632nmpodcast.substack.com/Follow our hosts!Michael Dubrovsky: https://x.com/MikeDubrovskyMisha Shalaginov: https://x.com/MYShalaginovXinghui Yin: https://x.com/XinghuiYinSubscribe:Apple Podcasts: https://podcasts.apple.com/us/podcast/632nm/id1751170269Spotify: https://open.spotify.com/show/4aVH9vT5qp5UUUvQ6Uf6ORWebsite: https://www.632nm.comTimestamps:00:00 - Intro01:25 - Working with George Church13:03 - Neuralink22:23 - Gap Maps31:47 - Artificial Ribosome36:45 - What is Convergent Research?40:03 - What are FROs?44:16 - What Made OpenAI So Successful?48:19 - Has AI Actually Impacted Science?52:15 - Notable FROs1:05:43 - Why Haven't There Been More Scientific Breakthroughs?1:09:47 - Lithography and Chip Design1:13:41 - We Can't Beat Insects1:16:45 - What Separates Good FROs1:18:40 - East vs West Coast Innovation1:27:21 - Research into Longevity1:33:27 - Advice for Grad Students1:39:40 - How to Get Involved in FROs#neuroscience #molecularbiology #quantumphysics #researchfunding #startups

Times have changed. And cesium clocks can't keep up.In this episode, we sit down with Jun Ye, Joint Institute for Laboratory Astrophysics (JILA) Fellow and pioneer of optical lattice clocks, whose work has pushed timekeeping far beyond traditional cesium atomic clocks. Ye explains how combining ultra-stable lasers, frequency combs, and ultra-cold atoms produces clocks more than 100× more precise than today’s standards: so sensitive they can detect gravitational time dilation across the width of a human hair.We explore how this next generation of atomic clocks may open windows onto gravitational waves, test Einstein’s relativity in new regimes, and even help build a GPS for space travel. Ye also shares his personal journey from growing up during China’s Cultural Revolution to becoming a leader in precision measurement, and what that experience taught him about resilience, mentorship, and protecting scientific inquiry.Whether you’re curious about time, relativity, quantum physics, GPS technology, or the frontiers of precision measurement, this conversation offers a rare insider’s look at how breakthroughs in timekeeping can lead to entirely new physics.Follow us for more technical interviews with the world’s greatest scientists:Twitter: https://x.com/632nmPodcastInstagram: https://www.instagram.com/632nmpodcast?utm_source=ig_web_button_share_sheet&igsh=ZDNlZDc0MzIxNw==LinkedIn: https://www.linkedin.com/company/632nm/about/Substack: https://632nmpodcast.substack.com/Follow our hosts!Michael Dubrovsky: https://x.com/MikeDubrovskyMisha Shalaginov: https://x.com/MYShalaginovXinghui Yin: https://x.com/XinghuiYinSubscribe:Apple Podcasts: https://podcasts.apple.com/us/podcast/632nm/id1751170269Spotify: https://open.spotify.com/show/4aVH9vT5qp5UUUvQ6Uf6ORWebsite: https://www.632nm.comTimestamps:00:00 - Intro01:17 - Why Haven't Optical Clocks Replaced Cesium Clocks?10:45 - Fundamentals of Optical Atomic Clocks17:34 - History of Atomic Clocks30:18 - What is JILA?35:01 - What brought Jun to JILA?39:33 - What does it take to get a PhD in Physics?42:40 - Jun Ye's PhD work44:36 - Limitations of Laser Stabilization50:38 - How Do We Make the Most Stable Lasers?57:28 - How to Measure Laser Coherence Times1:04:24 - Building Atomic Clocks from First Principles1:08:59 - Jun's Notable Accomplishments1:14:00 - Magic Frequencies for Optical Traps1:21:04 - Can AI Improve Atomic Clocks?1:24:00 - How Does Quantum Entanglement Affect Clocks?1:30:29 - Development of Quantum Computers1:34:23 - Pros and Cons of Nuclear Clocks1:43:49 - What Would Jun Do With Unlimited Research Funding?1:47:09 - Lessons from China's Cultural Revolution#quantumcomputing #quantumphysics #atomicclock #laser #physics #optics #astrophysics #astronomy #spacetime

How did cooling atoms with lasers revolutionize our understanding of time?In this episode, we speak with Bill Phillips, Nobel Laureate in Physics, about his groundbreaking work on laser cooling and trapping of atoms: research that not only won him the Nobel Prize but also transformed modern timekeeping and technology. Phillips explains why breaking the Doppler cooling limit changed physics forever and what it means that today’s clocks can measure time differences caused by moving a device just a few millimeters in Earth’s gravity.We discuss the history of timekeeping from sundials to atomic clocks, how Einstein’s relativity reshaped our view of time, and the serendipitous discovery of sub-Doppler cooling that opened the door to ultra-precise measurement, quantum computing, and fundamental tests of nature. Along the way, Phillips reflects on the culture of physics, the importance of mentorship, and the joy of discovery.Whether you’re curious about time, relativity, quantum physics, GPS technology, or the frontiers of precision measurement, this conversation offers rare insight into how science, collaboration, and curiosity converge to shape the modern world.Follow us for more technical interviews with the world’s greatest scientists:Twitter: https://x.com/632nmPodcastInstagram: https://www.instagram.com/632nmpodcast?utm_source=ig_web_button_share_sheet&igsh=ZDNlZDc0MzIxNw==LinkedIn: https://www.linkedin.com/company/632nm/about/Substack: https://632nmpodcast.substack.com/Follow our hosts!Michael Dubrovsky: https://x.com/MikeDubrovskyMisha Shalaginov: https://x.com/MYShalaginovXinghui Yin: https://x.com/XinghuiYinSubscribe:Apple Podcasts: https://podcasts.apple.com/us/podcast/632nm/id1751170269Spotify: https://open.spotify.com/show/4aVH9vT5qp5UUUvQ6Uf6ORWebsite: [https://www.632nm.com](https://www.632nm.com/)Timestamps:00:00 - Intro01:43 - What is Time?05:49 - How Did Bill Get Into Atom Cooling?18:30 - How Do Atomic Clocks Actually Work?31:08 - History of Atomic Clocks37:18 - Laser Cooling for Atomic Clocks40:49 - How To Synchronize Atomic Clocks43:20 - How Cesium Cooling Was Developed45:48 - Pushing Beyond the Doppler Limit49:47 - The Beginning of Thor Labs52:45 - The Previous Limits were Wrong1:05:37 - How Bill Broke the Doppler Limit1:12:22 - What is Optical Pumping?1:20:27 - Can Atom Trapping Be Leveraged For Cold Fusion?1:31:32 - What Makes Bill So Lucky?1:35:25 - How Bill's Work Led to Atomic Clocks1:41:05 - What Makes Cesium So Good For Atomic Clocks?1:47:38 - Quantum Effects on Atomic Clocks1:59:02 - Bose-Einstein Condensates2:09:05 - Did Bill's Work Lead To Quantum Computing?2:11:26 - Bill's Thoughts on the Future#billphillips #nobelprize #laser #atomicclock #dopplereffect #quantumcomputing #quantumphysics #gps #physics #boseeinsteincondensate #theoreticalphysics #relativity
