  • Causal Inference and Quantum Networks: How Hypothesis Testing from Statistical Data is relevant to Quantum Engineering
    Seminar:  Optics Seminar QUEST Center event:  Speaker:  Dr. Elie Wolfe, Perimeter Institute for Theoretical Physics, Waterloo, Canada Date :  26/08/2018 – 14:00 – 15:00 Place:  Room B-032 (ground floor) – Nanotechnology center Abstract:  Causal inference is a (classical) technique used to figure out what sorts of causal relationships between variables constitute a viable explanations for some observed statistics. Equivalently, causal inference allows us to quantify …
  • Light-induced coherence in an atom-cavity system
    Seminar:  Special Seminar QUEST Center event:  Speaker:  Andreas Hemmerich (Hamburg) Date :  30/07/2018 – 15:00 Place:  Resnick (#209) – room 210 Abstract:  We demonstrate light-induced formation of coherence in a cold atomic gas system that utilizes the suppression of a competing density wave (DW) order. The condensed atoms are placed in an optical cavity and pumped by an external optical standing wave, which induces a long-range interaction, mediated by photon sca …
  • Diffusion in Translucent Media
    Seminar:  Optics Seminar QUEST Center event:  Speaker:  Prof. Azriel Z. Genack, Queens College, New York Date :  13/06/2018 – 12:00 – 13:00 Place:  Nanotechnology – 9th floor seminar room Abstract:  Diffusion in Translucent Media Azriel Z. Genack,  Department of Physics, Queens College and Graduate Center of the City University of New York, Flushing, New York 11367 Diffusion is the result of repeated random scattering. It governs a wide range of phenomena from …
  • The effect of fiber nonlinearities in modern fiber-optic transmission
    Seminar:  Optics Seminar QUEST Center event:  Speaker:  Prof. Mark Shtaif, Electrical Engineering, Tel Aviv University Date :  11/04/2018 – 12:00 – 13:00 Place:  Nanotechnology center, 9th floor seminar room Abstract:  In the past decades optical fibers have become the main medium through which information is transmitted. Unlike most other forms of communications, the mechanism that puts an ultimate limit on the achievable data transmission rates in fibers is the op …
  • Strongly pumped SU(1,1) interferometer: loss-tolerant sensing below the shot-noise limit
    Seminar:  Optics Seminar QUEST Center event:  Speaker:  Maria Chekhova, Max Planck Institute for the Science of Light, Erlangen, Germany Date :  08/04/2018 – 14:00 – 15:00 Place:  Reznik Building 209, room 210 Abstract:  A nonlinear SU(1,1) interferometer is a sequence of two coherently pumped high-gain parametric amplifiers, realized through parametric down-conversion or four-wave mixing. The radiation emitted by the first amplifier can be amplified or deamplified …
  • Thermodynamics of small quantum systems and small environments
    Seminar:  Condensed Matter Resnick seminar QUEST Center event:  Speaker:  Raam Uzdin (Technion) Date :  18/01/2018 – 12:30 Place:  Resnick (#209) – room 210 Abstract:  With the rapid development of quantum technologies and the ability to manipulate individual atoms and ion, thermodynamics faces new challenges. The main question is not whether thermodynamics is valid, but whether it is relevant. Does it provide useful predictions on quantities of interest in the micr …
  • Fault-tolerant measurement of a quantum error syndrome
    Seminar:  Optics Seminar QUEST Center event:  Speaker:  Dr. Serge Rosenblum, Yale University Date :  17/01/2018 – 12:00 – 13:00 Place:  Nano-center, 9th floor seminar room Abstract:  Quantum error correction allows quantum computers to operate despite the presence of noise and imperfections. A critical component of any error correcting scheme is the mapping of a quantum error syndrome onto an ancilla qubit. However, errors occurring in the ancilla can propagate …
