Abstract

Superconducting circuits based on Josephson junctions exhibit macroscopic quantum coherence and can behave like artificial atoms. Recent technological advances have made it possible to implement atomic-physics and quantum-optics experiments on a chip using these artificial atoms. This review presents a brief overview of the progress achieved so far in this rapidly advancing field. We not only discuss phenomena analogous to those in atomic physics and quantum optics with natural atoms, but also highlight those not occurring in natural atoms. In addition, we summarize several prospective directions in this emerging interdisciplinary field.

    • According to the article, what they measured doesn't really sound like a 'real' quantum system: it's a superconducting circuit with two discrete states with an infinite number of previously immeasurable superposition states in between. They call this an 'artificial atom'. Unless…
