SUMMARY:Waiting time distribution and switching rate of a microwave ph
 oton detector based on a current–biased Josephson junction\, Co
 ndensed Matter Theory Group Seminar\, Amrit Poudel\, UW-Madison
DESCRIPTION:In this talk\, I will discuss methods to compute the effic
 iency of a microwave photon detector based on a current-biased Josephs
 on junction (JJ)\, which is either connected to a (driven) microwave r
 esonator or driven directly by a classical microwave source. Here I co
 nsider the evolution of the system in the presence of the environment 
 and tunneling events of the JJ to the voltage state. I will then discu
 ss how one can use the waiting time distribution to compute the averag
 e switching rate of the JJ and the efficiency of the photon detector. 
 Finally\, I will present a preliminary result on the condition for pow
 er matching between the detector\, which I treat as a linear oscillato
 r\, and the microwave source.
