DESCRIPTION:The 2025 Nobel Prize in Physics: A Brief History of Superconduc
 ting Qubits and Circuit Quantum Electrodynamics\n\nThe 2025 Nobel Prize in
  Physics was awarded to John Clarke\, Michel Devoret\, and John Martinis 
 “for the discovery of macroscopic quantum mechanical tunnelling and ener
 gy quantization in an electric circuit.”  This talk will give a brief hi
 story of their work and the remarkable developments that followed from it.
 \n\nCircuit QED is the quantum electrodynamics of superconducting microwav
 e circuits and is today the leading architecture for development of quantu
 m information processors based on superconducting qubits.  The study of su
 perconducting electrical circuits began in the 1960’s with the observati
 on of the Josephson effect.  Ideas by Anthony Leggett about macroscopic qu
 antum tunneling led to remarkable experiments in the Clarke group at Berke
 ley in the 1980’s demonstrating that the superconducting order parameter
  was a quantum mechanical degree of freedom exhibiting energy level quanti
 zation\, and quantum tunneling.  This in turn led to the invention of nume
 rous species of superconducting qubits which have advanced in the last 25 
 years by a factor of nearly 106 in coherence time.  These advances have op
 ened up a completely new regime of strong-coupling non-linear optics in th
 e microwave domain whose parameters and capabilities are dramatically diff
 erent from traditional optical cavity QED.  They have also led to enormous
  progress in industrial scaling up of the technology and have brought us i
 nto the beginnings of the era of quantum error correction.  We may now be 
 standing close to the boundary of the ‘NISQ’ era and the coming era of
  fault-tolerant quantum machines.
