Optimal Diffractive Focusing of Vortex Beams
Roohollah Ghobadi, Carrie Rodriguez, Lukas Scarfe +2
We formulate diffractive ring focusing of paraxial beams carrying orbital angular momentum (OAM) through a finite circular aperture as a variational optimization problem. For a fix…
Investigating the Performance of Adaptive Optics on Different Bases of Spatial Modes in Turbulent Channels
Rojan Abolhassani, Lukas Scarfe, Francesco Di Colandrea +3
Quantum key distribution (QKD) allows secure key exchange based on the principles of quantum mechanics, with higher-dimensional photonic states offering enhanced channel capacity a…
Programmable photonic quantum walks on lattices with cyclic, toroidal, and cylindrical topology
Alessio D'Errico, Nazanin Dehghan, Maria Gorizia Ammendola +5
Photonic implementations of unitary processes on lattice structures, such as quantum walks, have been demonstrated across various architectures. However, few platforms offer the co…
Compact and programmable large-scale optical processor in free space
Maria Gorizia Ammendola, Nazanin Dehghan, Lukas Scarfe +4
Photonic circuits are central to classical and quantum information processing. While integrated technologies dominate, free-space architectures are emerging as attractive alternati…
High-Dimensional Quantum Key Distribution with Qubit-like States
Lukas Scarfe, Rojan Abolhassani, Frédéric Bouchard +4
Quantum key distribution (QKD) protocols most often use two conjugate bases in order to verify the security of the quantum channel. In the majority of protocols, these bases are mu…
Spatial Mode Encoding for Quantum Key Distribution: From Hundreds to Thousands of Modes
Lukas Scarfe, Yingwen Zhang, Ebrahim Karimi
Here, we present a proof-of-principle high-dimensional quantum key distribution (QKD) protocol utilizing the position and momentum entanglement of photon pairs. The protocol exploi…
Predicting atmospheric turbulence for secure quantum communications in free space
Tareq Jaouni, Lukas Scarfe, Frédéric Bouchard +4
Atmospheric turbulence is the main barrier to large-scale free-space quantum communication networks. Aberrations distort optical information carriers, thus limiting or preventing t…
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…
