Dr. Forn-Díaz has participated in a joint work with the group of Prof. Chris Wilson at IQC Waterloo on the area of generation of entangled states of microwave generation, which has just been published to Physical Review Applied. The work, part of which was carried out during Pol’s postdoctoral position at Prof. Wilson’s lab, focuses on a nonlinear multimode resonator that generates entangled states of radiation by the application of external pumping fields at the suitable driving frequencies. The key aspect of the circuit is the presence of a SQUID at the end of the line which mediates the interaction between different modes. This work is very important for the generation of nonclassical states of microwave radiation, which are applicable in the area of quantum communication and quantum sensing.
