Quantum light and sound

Andrew Cleland, Professor of Physics, University of California, Santa Barbara


I will present a description of recent experiments at UC Santa Barbara demonstrating coherent control of individual quanta of light (in the microwave band) and sound (also in the microwave band). In the experiments, electronic quantum bits are used to control and measure these quanta, and can generate both Fock number states and their superpositions, and store them either in an electromagnetic or in a mechanical resonator. If time permits, more recent work will be presented showing NOON state generation in a pair of electromagnetic resonators, representing quantum entanglement of microwave photons over a distance of a few millimeters.
