Random access quantum information processing in multimode cavities 2

ORAL

Abstract

A multimode superconducting cavity coupled to a single superconducting transmon circuit can be used to realize quantum information processors in which quantum logic gates between arbitrary pairs of cavity modes can be performed with equal ease using sideband transitions with the transmon [1]. Such random access processors allow efficient pulse sequences for realizing different families of multimode entangled states of arbitrary cavity modes, as well as three-mode gates such as the Toffoli and controlled-SWAP. We discuss methods for creating Dicke, GHZ and Cluster states, and interferometric methods for characterizing their entanglement using multimode quantum gates [2].\\
