Phys. Rev. Lett. 98, 207001 (2007) [4 pages]Wideband Detection of the Third Moment of Shot Noise by a Hysteretic Josephson JunctionReceived 4 December 2006; published 16 May 2007 We use a hysteretic Josephson junction as an on-chip detector of the third moment of shot noise of a tunnel junction. The detectable bandwidth is determined by the plasma frequency of the detector, which is about 50 GHz in the present experiment. The third moment of shot noise results in a measurable change of the switching rate when reversing polarity of the current through the noise source. We analyze the observed asymmetry assuming adiabatic response of the detector. © 2007 The American Physical Society URL:
