What Happens During a Quantum Jump?

Oct 24, 2026 · 16m

Summary

This episode explores the century-old debate between Niels Bohr and Erwin Schrödinger over the nature of quantum jumps, contrasting the Copenhagen interpretation's view of instantaneous, random transitions with Schrödinger's belief in continuous, deterministic processes. It details how recent experiments using superconducting circuits have revealed that quantum jumps are not instantaneous but follow a predictable trajectory, allowing researchers to even reverse them mid-flight.
