Abstract
The ability to manipulate photonic states is an important tool for quantum information processing. In cavity quantum electrodynamics (QED), coupling between bosonic modes has, until now, required a qubit to mediate the interaction. As an alternative, it is also possible to generate this coupling using parametric frequency conversion. In this work, we accomplish this in a superconducting microwave circuit by parametrically coupling resonator harmonics, realizing a generalized beam- splitter interaction between cavity modes. We demonstrate this by coherently manipulating a single photon Fock state in a strongly-coupled mode basis. This introduces a new tool for circuit-based QED, creating a linear optical element that had previously been confined to propagating waves and extends the possibilities for the developing field of quantum microwave photonics.Citation
