The 632nm team sat down with MIT professor Seth Lloyd for a mind-bending journey through quantum mechanics, information theory, and the early days of quantum computing. Lloyd shares fascinating stories from his pioneering work in quantum information, including how he nearly got expelled from his PhD program for pursuing what was then considered a "crazy" research direction. Through engaging examples and personal anecdotes, he explains why quantum mechanics is "irreducibly weird" and how information and entropy are fundamentally the same thing.

The conversation takes unexpected turns with remarkable stories about Stephen Hawking's quantum gravity lectures, Richard Feynman's three tricks that revolutionized physics, and epic MIT student pranks including the great Caltech cannon heist. Lloyd also tackles deep questions about consciousness, free will, and the computational nature of the universe, explaining why the universe itself may be its own most efficient simulation. His unique perspective as both a mechanical engineer and quantum physicist brings fresh insights to some of science's most profound mysteries.

In this eye-opening episode, former Zapata Computing CEO Yudong Chen reveals the sobering truth about quantum computing's potential impact on drug discovery and the industry's inflated market expectations. Chen explains why even with perfect quantum chemistry calculations, the business case for quantum computing in pharmaceuticals falls dramatically short of the billions being invested, with a total addressable market of only around $100M.

The conversation takes fascinating turns as Chen shares the unusual origin story of Zapata Computing, named after Mexican revolutionary Emiliano Zapata, and traces the company's journey from quantum computing to AI. He provides crucial insights into the field's future, discussing the emerging quantum winter and why government funding, rather than venture capital, may be the path forward.

Dr. David Huang shares the remarkable journey of how a failed laser surgery project during his MD-PhD studies at MIT led to the invention of Optical Coherence Tomography (OCT), now used in over 40 million eye procedures annually. The story includes a pivotal moment when Professor James Fujimoto volunteered as the first human subject for OCT testing when no other students would agree to have an experimental laser pointed at their eye.

The development of OCT was made possible by the 1980s telecommunications boom, which provided crucial fiber optic components. Dr. Huang's unique background combining computer science and medicine proved essential for creating this breakthrough technology. The conversation also explores OCT's rapid commercialization, its impact on treating age-related macular degeneration, and future developments including smartphone-based screening and potential applications for diagnosing brain and heart disease through retinal imaging.
