Engineering qubit dynamics in open systems with photonic synthetic lattices
Francesco Di Colandrea, Tareq Jaouni, John Grace +4
The evolution of a quantum system interacting with an environment can be described as a unitary process acting on both the system and the environment. In this framework, the system…
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…
On the Electromagnetic Mass Dilemma
Qasem Exirifard, Alessio D'Errico, Ebrahim Karimi
We show that a charged sphere moving at a constant velocity exhibits a mass due to electromagnetic radiation, expressed as , where is the electromagn…
Biphoton State Reconstruction via Phase Retrieval Methods
Nazanin Dehghan, Alessio D'Errico, Francesco Di Colandrea +1
The complete measurement of the quantum state of two correlated photons requires reconstructing the amplitude and phase of the biphoton wavefunction. We show how, by means of spati…
A genetic algorithm for the response of twisted nematic liquid crystals to an applied field
Alicia Sit, Francesco Di Colandrea, Alessio D'Errico +1
When an external field is applied across a liquid-crystal cell, the twist and tilt distributions cannot be calculated analytically and must be extracted numerically. In the standar…
Quantum process tomography of structured optical gates with convolutional neural networks
Tareq Jaouni, Francesco Di Colandrea, Lorenzo Amato +2
The characterization of a unitary gate is experimentally accomplished via Quantum Process Tomography, which combines the outcomes of different projective measurements to reconstruc…
