  • Why Do Quantum Computers Make So Many Mistakes? | Mikhail Lukin on Quantum Error Correction
    2025/10/21

    You can’t copy a qubit. So how do quantum computers remember anything?

    In this episode, we sit down with Mikhail Lukin, Harvard physicist and co-director of the Harvard Quantum Initiative, whose lab is building quantum computers from arrays of individually trapped atoms. Lukin explains the paradox of quantum error correction—how you can safeguard quantum information even though it can’t be copied or measured directly—and why this breakthrough may be the key to making large-scale quantum computers possible.

    We dive into the strange logic of superposition, entanglement, and “small cat states,” explore what makes quantum evolution inherently analog, and learn how Lukin’s team uses optical tweezers and Rydberg interactions to engineer stable, reconfigurable qubits—atoms literally held and moved by light.

    Whether you’re fascinated by quantum mechanics, computing, Schrödinger’s cat, or the future of information, this conversation reveals how physicists are turning the weirdness of quantum physics into working technology—and why building a fault-tolerant quantum computer is one of the hardest and most exciting challenges in science today.

  • What Science can Learn from Startups | Adam Marblestone on Focused Research Organizations
    2025/10/07

    Science has stalled. And Adam Marblestone thinks he knows why.

    Check out the Research Gap Map here: https://www.gap-map.org/?sort=rank

    In 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.

  • What Optical Atomic Clocks Tell Us About Space-Time | Jun Ye
    2025/09/23

    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.

  • Laser Cooling and Quantum Timekeeping | Bill Phillips
    2025/09/09

    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.

  • Inside the Battle for Psychedelic Therapy | Rick Doblin
    2025/08/26

    What does it take to turn a banned psychedelic into an FDA-approved medicine?

    Visit MAPS to read about the latest progress is psychedelic research: https://maps.org/

    In this episode, we speak with Rick Doblin, founder of the Multidisciplinary Association for Psychedelic Studies (MAPS), about the decades-long mission to make MDMA-assisted therapy a legal treatment for PTSD and other mental health conditions. Rick received his PhD from Harvard's Kennedy School of Government in public policy focusing on the regulation of medical use of psychedelics in 2001. Rick shares the science behind MDMA’s therapeutic effects, the strategy for winning over regulators, and the battles over claims of neurotoxicity. We discuss the history of psychedelic research, the rise of the underground therapy movement, and how clinical trials, policy change, and cultural perception must align to move psychedelics from stigma to science.

    Whether you’re curious about psychedelic science, drug policy reform, FDA clinical trials, or the future of mental health treatment, this conversation delivers expert insight into the intersection of research, regulation, and real-world impact.
