Cornerstone for Superconducting Quantum Computing--Macroscopic Quantum Effects in Circuits：Comment on 2025 Nobel Prize in Physics

The Nobel Prize in Physics 2025 was awarded jointly to John Clarke，Michel H. Devoret and John M. Martinis “for the discovery of macroscopic quantum mechanical tunnelling and energy quantization in an electric circuit”. Their landmark research validated the laws of quantum mechanics at the macroscopic scale，breaking the traditional notion that quantum behavior is confined to the microscopic realm. This breakthrough directly catalyzed the advent of superconducting quantum computing and has been hailed as “opening a door to quantum technologies.”
