• Abstract: The prospect of developing more efficient classical or quantum photonic devices through the suppression of backscattering is a major driving force for the field of topological photonics. However, genuine protection against backscattering in photonics requires implementing architectures with broken time-reversal which is technically challenging. Here, we make use of a frequency-encoded synthetic dimension scheme in an optical fibre loop platform to experimentally realise a photonic Chern insulator inspired from the Haldane model where time-reversal is explicitly broken through temporal modulation. The bands' topology is assessed by reconstructing the Bloch states' geometry across the Brillouin zone. We further highlight its consequences by measuring a driven-dissipative analogue of the quantized transverse Hall conductivity. Our results thus open the door to harnessing topologically protected unidirectional transport of light in frequency-multiplexed photonic systems.

  We propose an efficient decomposition scheme for a quantum receiver that attains the Helstrom bound in the low-photon regime for discriminating binary coherent states. We account for realistic conditions by examining the impact of photon loss and imperfect photon detection, including the presence of dark counts. Our scheme motivates testing quantum advantages with cubic-phase gates and designing photonic quantum computers to optimize symbol-by-symbol measurements in optical communication.

• Shaping entangled photons through thick scattering media using an advanced wave beacon [0.0]
  Entangled photons propagate through a complex medium such as a biological tissue or a turbulent atmosphere. Using wavefront shaping to compensate for the scattering and retrieve the two-photon correlations is challenging due to the low signal-to-noise ratio. We propose and demonstrate a new feedback mechanism that is inspired by Klyshko's advanced wave picture.
