Two-photon interference: the Hong-Ou-Mandel effect
FrédÉric Bouchard, Alicia Sit, Yingwen Zhang +5
Nearly 30 years ago, two-photon interference was observed, marking the beginning of a new quantum era. Indeed, two-photon interference has no classical analogue, giving it a distin…
Underwater quantum communication over a 30-meter flume tank
Felix Hufnagel, Alicia Sit, Frédéric Bouchard +5
Underwater quantum communication has recently been explored using polarization and orbital angular momentum. Here, we show that spatially structured modes, e.g., a coherent superpo…
Characterization of an underwater channel for quantum communications in the Ottawa River
Felix Hufnagel, Alicia Sit, Florence Grenapin +8
We examine the propagation of optical beams possessing different polarization states and spatial modes through the Ottawa River in Canada. A Shack-Hartmann wavefront sensor is used…
Quantum process tomography of a high-dimensional quantum communication channel
Frédéric Bouchard, Felix Hufnagel, Dominik Koutný +5
The characterization of quantum processes, e.g. communication channels, is an essential ingredient for establishing quantum information systems. For quantum key distribution protoc…
Round-Robin Differential Phase-Shift Quantum Key Distribution with Twisted Photons
Frédéric Bouchard, Alicia Sit, Khabat Heshami +2
Quantum key distribution (QKD) offers the possibility for two individuals to communicate a securely encrypted message. From the time of its inception in 1984 by Bennett and Brassar…
Underwater Quantum Key Distribution in Outdoor Conditions with Twisted Photons
Frédéric Bouchard, Alicia Sit, Felix Hufnagel +8
Quantum communication has been successfully implemented in optical fibres and through free-space [1-3]. Fibre systems, though capable of fast key rates and low quantum bit error ra…
