  1. 49. Revealing hidden photons: imperfect photocounting measurements and their applications
    Prof. Andrii Semenov (Bogolyubov Institute for Theoretical Physics, National Academy of Sciences of Ukraine)
    11/8/24, 8:05 AM
    Invited Talk

    In quantum optics it is widely believed that all measurements with coherent states of light and their statistical mixtures can be explained without the need to quantize the electromagnetic field. Quantum states that do not satisfy this condition are considered to be nonclassical. Nowadays, optical nonclassicality is often considered as an important resource for creating quantum entanglement...

    Oral

    An optical state is considered nonclassical if its density operator cannot be represented as a statistical mixture of coherent states. This definition renders prominent phenomena such as sub-Poissionian statistics of photon counts or quadrature squeezing nonclassical. However, determining whether an optical state is nonclassical is a challenging task since it requires tomographic...

  3. 43. Realistic Photon-Number Resolution and Its Impact on Gaussian Boson Sampling
    Ivan Yeremenko (Bogolyubov Institute for Theoretical Physics of the National Academy of Sciences of Ukraine)
    11/8/24, 8:50 AM
    Oral

    Gaussian boson sampling (GBS) (see Ref. [1]) is a promising quantum computing model that exploits photonic systems to perform computations beyond the reach of classical methods. A crucial aspect of GBS is the detection of photon patterns at the output of an interferometer. However, most experiments rely on on-off detectors that can only identify whether photons are present, without resolving...

  4. 73. Quantum light in atmospheric turbulence
    Mykyta Klen (Bogolyubov Institute for Theoretical Physics, NAS of Ukraine, Vul. Metrologichna 14b, 03143 Kyiv, Ukraine)
    11/8/24, 9:05 AM
    Oral

    Quantum communication is a rapidly developing field focused on enhancing the security of communication protocols and new methods of information exchange. These techniques use quantum light propagating through glass fibers or free space as the information carrier. While the free-space channels are useful in many practical scenarios, they face challenging problems due to fluctuations in the...

  5. 132. Optical Emulation of Rabi coupling for Sensing Applications
    Dr Hamid Pashaei Adl (Institut de Ciència dels Materials (ICMUV), Universitat de València. Catedrático José Beltrán 2, 46980 Paterna, Valencia, Spain.)
    11/8/24, 9:20 AM
    Oral

    Optical systems are at the forefront of modern technologies, from telecommunications to quantum computing, offering unparalleled speed and efficiency in data processing and transmission. To develop and optimize these systems, engineers and scientists rely on tools like optical emulators. These tools play a critical role in modeling, testing, and refining optical networks, devices, and...
