 Measuring the number of photons in a microwave mode</a>\nby Benjamin Huard
  (ENS Lyon) as part of Centre for Quantum Software and Information Seminar
  Series\n\n\nAbstract\nCounting the number of photons in an electromagneti
 c mode is an important tool for quantum information processing. In order t
 o perform a single shot measurement\, one usually encodes information abou
 t the photon number into a qubit state and read out the qubit. Repeating t
 his procedure while varying the encoded single bit of information enables 
 to pinpoint the number of photons. In this talk\, I will present two exper
 iments that address two main challenges in photocounting. \n\nFirst\, I wi
 ll show how one can avoid the sequential repetition of qubit measurements 
 and instead use a single superconducting qubit in order to multiplex the m
 easurement of the photon number in a stationary microwave mode.\n\nSecond\
 , I will show how we could convert a stationary mode counter into a photoc
 ounter of traveling wave packets using a quantum memory.\n\nHosted by Nath
