Spectral tuning of single T centres by the Stark effect
Michael Dobinson, Felix Hufnagel, Simon A. Meynell +8
Among the many solid-state emitters being explored for scalable quantum technologies, the silicon T centre is a leading candidate offering long-lived spin qubits, a telecommunicati…
Fast Adaptive Optics for High-Dimensional Quantum Communications in Turbulent Channels
Lukas Scarfe, Felix Hufnagel, Manuel F. Ferrer-Garcia +3
Quantum Key Distribution (QKD) promises a provably secure method to transmit information from one party to another. Free-space QKD allows for this information to be sent over great…
Full-mode Characterisation of Correlated Photon Pairs Generated in Spontaneous Downconversion
Alessio D'Errico, Felix Hufnagel, Filippo Miatto +2
Spontaneous parametric downconversion is the primary source to generate entangled photon pairs in quantum photonics laboratories. Depending on the experimental design, the generate…
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…
Compressed sensing of twisted photons
F. Bouchard, D. Koutny, F. Hufnagel +8
The ability to completely characterize the state of a quantum system is an essential element for the emerging quantum technologies. Here, we present a compressed-sensing inspired m…
