  1. Low Noise Single Electron Source Jin Zhang , Y. Sherkunov, N. d’Ambrumenil, B. Muzykantskii University of Warwick, U.K.

  2. Noise Generation T Minimized when Single particle excitation: Ivanov et.al, 1997 for abrupt opening T ? T 0 0 t t

  3. Minimize Equilibrium Noise 1. Single Lorentzianpulse to the barrier 2. Double Lorentzian pulses to the barrier when

  4. Single Electron Sourcewith Suppressed Equilibrium Noise Total noise due to an MES: Probability Distribution arXiv:0812.4433v3YS JZ NdA BM

  5. Theory onFull Counting Statistics (I) Characteristic Function Current, Noise, etc... Understood with density matrix of outgoing states:

  6. Theory onFull Counting Statistics (II) Abanovet.al 2008

  7. Conclusion • We proposed a smooth way to open the barrier, which could be used as a single electron source at low temperatures without divergent equilibrium noise.
