Photocount statistics of the Josephson parametric amplifier
نویسندگان
چکیده
Parametric amplifiers are known to squeeze the vacuum state of electromagnetic field, which results in predictable statistics photocounts at their output. However, recent theoretical work arXiv:1112.4159 predicts a very different statistical distribution for an amplifier based on Josephson junction. We test hypothesis experimentally and recover expected squeezed statistics. explain this discrepancy by showing theoretically how photocount is dictated detection process, from single mode (our experiment) multimode, fully resolved frequency (as arXiv:1112.4159).

Statistics of radiation at Josephson parametric resonance
Motivated by recent experiments, we study theoretically the full counting statistics of radiation emitted below the threshold of parametric resonance in a Josephson-junction circuit. In contrast to most optical systems, a significant part of emitted radiation can be collected and converted to an output signal. This permits studying the correlations of the radiation. To quantify the correlations...
متن کاملControlling the dynamic range of a Josephson parametric amplifier
*Correspondence: [email protected] Department of Physics, ETH Zürich, Zürich, 8093, Switzerland Abstract One of the central challenges in the development of parametric amplifiers is the control of the dynamic range relative to its gain and bandwidth, which typically limits quantum limited amplification to signals which contain only a few photons per inverse bandwidth. Here, we discuss the c...
متن کاملPhotocount statistics in mesoscopic optics.
We report the first observation of the impact of mesoscopic fluctuations on the photocount statistics of coherent light scattered in a random medium. A Poisson photocount distribution of the incident light widens and gains additional asymmetry upon transmission through a suspension of small dielectric spheres. The effect is only appreciable when the average number n of photocounts becomes compa...
متن کاملA near-quantum-limited Josephson traveling-wave parametric amplifier.
Detecting single-photon level signals—carriers of both classical and quantum information—is particularly challenging for low-energy microwave frequency excitations. Here we introduce a superconducting amplifier based on a Josephson junction transmission line. Unlike current standing-wave parametric amplifiers, this traveling wave architecture robustly achieves high gain over a bandwidth of seve...
