This chapter describes a method to control and measure quantum cavities, achieved using a superconducting phase qubit, a type of electronic atom. The phase qubit has been under intensive development for use as a quantum processing element in a quantum computer. It has recently been used to demonstrate the quantum control and measurement of excitations in resonant cavities, including controlling photons in superconducting microwave resonators, as well as phonons in microwave-frequency mechanical resonators. The discussion here focuses on the quantum control of electromagnetic resonators.

Keywords: qubit; photon; phonon; ground state; quantum coherence
