DESCRIPTION:Speaker: Zenghui Bao\nhosted by Johannes Fink\nAbstract: Circui
 t QED allows the realization of strong and controllable light-matter inter
 action in superconducting circuit at the quantum level in unprecedented de
 tail. This provides a powerful platform to study the manipulation of micro
 wave photon and demonstrate microwave photonic devices applicable in quant
 um network and quantum information processing. This talk will be divided i
 nto two parts to introduce our research on manipulation\, storage\, and ge
 neration of microwave photons in superconducting circuit. In the first par
 t\, I will introduce a versatile and highly scalable approach to prepare g
 eneralized and multipartite cat states for itinerant microwave photon. Thi
 s approach is based on the cavity assisted qubit-photon interaction. With 
 the same interaction\, we have also realized a  single photon transistor i
 n microwave regime with gain up to 53.4dB and extinction ratio above 20dB.
  In the second part\, I will introduce our research based on frequency tun
 able CPW resonator\, including the realization of on-demand storage and re
 trieval of weak coherent microwave photon pulses using a multiresonator qu
 antum memory\, and the demonstration  of a cryogenic coherent microwave pu
 lse generator.
