Description
Observations of quantum behavior in macroscopic systems have been reported for the past decades. Experiments on microwave-driven Josephson system have been a particularly rich source of data due to the simplicity of the Josephson relationships and the direct physical manipulation of the devices. We review key experiments through anomalous resonances, Rabi-oscillations, Ramsey fringes and other related types of measurements, such as qubit entanglement. However, we take the approach of investigating the observations through the well-accepted, non-quantized Resistively and Capacitively Shunted Josephson (RCSJ) model.
