Superconducting circuits can be used as artificial atoms and I will discuss how they can be used to study new physics. In particular, I will show how artificial atoms can be used to study vacuum fluctuations by placing the atom in front of a mirror and how they can be used to generate nonclassical states of microwaves. I will also show how these atoms can be coupled to sound such that they decay by emitting single phonons instead of single photons. Sound coupled atoms can also act as giant atoms, which leads to new physics in terms of large Lamb shifts and non-exponential decay.
