Quantum mechanics was supposed to be the law of the ultra-small — electrons, photons, particles dancing in mystery. But the 2025 Nobel Prize in Physics shattered that boundary. John Clarke, Michel Devoret, and John Martinis proved that quantum weirdness can rule over circuits you can literally hold in your hand. In this episode, we explore how their work on macroscopic quantum tunneling and energy quantization dragged quantum physics out of the atomic scale and into the tangible world—laying the foundation for quantum computers, sensors, and technologies that could reshape everything from medicine to encryption.
