Leggett's Idea: Make a Circuit a Quantum Object

Hosted by Lester Nare and Krishna Choudhary, this one-episode special brings all three 2025 Nobel Prizes in the sciences into a single listen: Medicine (immune tolerance and FOXP3), Physics (macroscopic quantum tunneling in superconducting circuits), and Chemistry (metal–organic frameworks and “new rooms for chemistry”).

Summary

• Medicine: Regulatory T cells and the FOXP3 gene that prevent autoimmune disease.
• Physics: Macroscopic quantum tunneling and energy quantization in electrical circuits — the bridge to today’s qubits.
• Chemistry: Metal–Organic Frameworks (MOFs) — modular porous crystals enabling CO₂ capture, water harvesting, and hydrogen storage.
