DESCRIPTION:Speaker: Yutaka Shikano\nhosted by Martin Zemlicka (RG Fink)\nA
 bstract: Abstract: A superconducting qubit is one of the leading physical 
 devices on quantum information processing in 20 years. As applications\, t
 here are scalable quantum computer and quantum sensing devices. Here\, we 
 propose a new detection scheme of axions through a quantum nondemolition d
 etection of quanta of collective spin excitations\, or magnons. As a semin
 al work of a emeging field\, quantum magnonics\, the hybrid quantum system
  between the Kittle mode of magnon and the superconducting qubit is demons
 trated. Furthermore\, resolving the number of the magnon through the super
 conducting qubit was done. By using this hybrid quantum device\, we obtain
  an upper limit on the coupling constant between axions and electrons. Thi
 s is the  rst experimental result using a quantum nondemolition detection 
 method in an axion detector.
