Abstract

Microscopic particles, as described by quantum mechanics, exhibit remarkable properties that fundamentally distinguish them from the macroscopic classical world: energy quantization, quantum tunneling, quantum superposition, and quantum entanglement, among others. This talk will explore the fundamental question of the boundary between quantum and classical worlds. It will introduce Anthony Leggett's foundational work in this area, and analyze the experimental observations of macroscopic quantum mechanical tunneling and energy quantization in a superconducting circuit, as recognized by the 2025 Nobel Prize in Physics.
