• Abstract: In this article, we introduce a framework for entanglement quantification of photon pairs represented by two-qubit Werner states. The measurement scheme is based on the symmetric informationally complete POVM. To make the framework realistic, we impose the Poisson noise on the measured two-photon coincidences. For various settings, numerical simulations were performed to evaluate the efficiency of the framework.

  We show that engineered loss, using an auxiliary waveguide, allows one to invert the spatial statistics from bunching to antibunching. We study the photon statistics within the loss-emulating channel and observe photon coincidences, which may provide insights into the design of quantum photonic integrated chips.

  We introduce a unifying framework describing the Photon-resolved Floquet theory and the standard full-counting statistics. Within this framework we analyze the two-mode Jaynes-Cummings model to demonstrate that the Photon-resolved Floquet theory and the standard full-counting statistics make consistent statistical predictions. We find that the photon-flux fluctuations diverge for vanishing dissipation, which can be related to an entanglement effect between the driven matter system and the driving field.

• Imperfect photon detection in quantum illumination [0.0]
  In quantum illumination, various detection schemes have been proposed for harnessing remaining quantum correlations of the entanglement-based resource state. We investigate the performance of this scheme for realistic detection parameters in terms of detection efficiency, dark count probability, and photon number resolution. We find that the requirements for photon number resolution in the two mixer outputs are highly asymmetric due to different associated photon number expectation values.

  We investigate a framework for binary image denoising via restricted Boltzmann machines (RBMs) The denoising objective is attained by balancing the distribution learned by a trained RBM with a penalty term for derivations from the noisy image. While we frame the model as an image denoising model, it can be applied to any binary data.

  We study a system of two interacting, non-indentical quantum emitters driven by a coherent field. We show that the features imprinted by the two-photon dynamics into the spectrum of resonance fluorescence are particularly sensitive to changes in the distance between emitters. This can be exploited for applications such as superresolution imaging of point-like sources.

  We introduce a numerical framework for quantum tomography and entanglement quantification of three-qubit generalized Werner states. The scheme involves the single-qubit SIC-POVM, which is then generalized to perform three-qubit measurements. As a special case, we compare the efficiency of the framework for the pure three-qubit generalized Werner state and the W state.
