Building Exotic Quantum Systems with Atoms and Photons in Low Dimensions


Quantum networks are composed of quantum nodes that interact coherently through quantum channels, and open a broad frontier of scientific opportunities. For example, a quantum network can serve as a ‘web’ for connecting quantum processors for quantum computation and communication, or as a ‘simulator’ allowing investigations of quantum critical phenomena arising from interactions among the nodes mediated by the channels.

In this talk, I will discuss a series of recent experiments, where magnons in atomic ensembles are strongly coupled to optical modes, and provide efficient means for the coherent control of entangled states between matter and light. I will also describe recent endeavors to integrate these quantum elements into quantum circuits with nanoscale optical structures, and discuss future prospects of probing stationary entanglement behaviours in driven, dissipative dipolar many-body quantum networks.
