Research interests

Professor Bienvenu Ndagano’s research program focuses on exploiting the multi-dimensional properties of photons for communication, imaging and sensing purposes. In particular, this research program explores:

  • Engineering of entangled states in the spatial and temporal domain
  • Transport of entangled states in complex media
  • Quantum microscopy
  • Detection of entangled states in high dimensions
  • Imaging of quantum correlations
  • Quantum sensing assisted by non-linear processes
  • Non-linear transfer of quantum entanglement in high-dimension

(a) Engineered sample etched in glass and measured with a profilometer. (b) The sample is not visible on the intensity image after illumination. (c) Low-resolution correlation image of the sample obtained from coincidence counting. (d) High-resolution correlation image of the sample obtained from combining low resolution images of the sample shifted transversally. (e) depth profile of the sample estimated from the high-resolution correlation image. Nature Photonics 16, 384–389 (2022)

 

(a) Two equivalent quantum and classical scenarios in which Alice send a photon from a non-separable state; in the quantum picture, Alice sends a photon from an entangled pair while in the classical picture, she sends one photon, of which only one degree of freedom is affected. (b) The degree of non-separability in both scenarios varies identically with perturbation strength (SR). Nature Photonics 13, 397–402 (2017)

 

(a) Shows the intensity of a twin beam of photon pairs onto a SPAD camera sensor. From many intensity measurement, one reconstructs the spatial conditional intensity distribution of a photon from a pair, given that it’s partner was previously measured at (b) A or (c) B. npj Quantum Information 6, 94 (2020)

Professor Bienvenu Ndagano holds the Quebec’s Ministry of Economy and Innovation Chair in Quantum Photonics (2023-2026). Originally from Bukavu in the Democratic Republic of Congo, Bienvenu Ndagano holds a doctorate (2018) in physics from the University of the Witwatersrand in South Africa. He worked as a postdoctoral researcher at the University of Glasgow from 2018 to 2021, before joining the Fraunhofer Center for Applied Photonics, still in Glasgow from 2021 to 2023. He takes up his post as Associate Professor at the Center for Energy Materials Telecommunications at the National Institute for Scientific Research in Varennes in 2023
